tests(refactor): mail_lmtp_ip.bats (#3004)

* chore: Drop ENV `ENABLE_POSTFIX_VIRTUAL_TRANSPORT`

* tests(chore): Remove redundant `dovecot-lmtp` config

None of this is needed. Only relevant change is changing the LMTP service listener for Dovecot and that can be delegated to `user-patches.sh`.

* tests(refactor): Use `user-patches.sh` instead of replacing config file

The only relevant changes in `test/config/dovecot-lmtp` regarding LMTP was:
- `/etc/dovecot/dovecot.conf` (`protocols = imap lmtp`) and `/etc/dovecot/protocols.d/` (`protocols = $protocols lmtp`).
- `conf.d/10-master.conf` only changed the LMTP service listener from a unix socket to TCP on port 24 (_this was the only change required for the test to pass_).

None of those configs are required as:
- `protocols = imap pop3 lmtp` [is the upstream default](https://doc.dovecot.org/settings/core/#core_setting-protocols), no need to add `lmtp`.
- The LMTP service listener is now configured for the test with `user-patches.sh`.

* tests(refactor): `mail_lmtp_ip.bats`

- Converted to new testing conventions and common container helpers.
- `ENABLE_POSTFIX_VIRTUAL_TRANSPORT` was not relevant, dropped.
- Revised test cases, logic remains the same.
- Large custom config used was not documented and doesn't appear to serve any purpose. Simplified by replacing with a single modification with `user-patches.sh`.
- Added some additional comments for context of test and improvements that could be made.

* tests(chore): Adjust comments

The comment from `mail_hostname` provides no valid context, it was likely copied over from `tests.bats` in Oct 2020 by accident.

The email sent is just for testing, nothing relevant to LMTP.

---

Added additional comment for test to reference extra information from.

* tests(chore): Update similar log line matching

Extracts out the match pattern and formatting commands into separate vars (reduces horizontal scrolling), and includes extra docs about what the matched line should be expected to look like.

-#           will need write access to that directory.
-#  dotlock_try: Same as dotlock, but if it fails because of permissions or
-#               because there isn't enough disk space, just skip it.
-#  fcntl  : Use this if possible. Works with NFS too if lockd is used.
-#  flock  : May not exist in all systems. Doesn't work with NFS.
-#  lockf  : May not exist in all systems. Doesn't work with NFS.
-#
-# You can use multiple locking methods; if you do the order they're declared
-# in is important to avoid deadlocks if other MTAs/MUAs are using multiple
-# locking methods as well. Some operating systems don't allow using some of
-# them simultaneously.
-#
-# The Debian value for mbox_write_locks differs from upstream Dovecot. It is

-# changed. If the mbox is large this can take a long time. Since the change
-# is usually just a newly appended mail, it'd be faster to simply read the
-# new mails. If this setting is enabled, Dovecot does this but still safely
-# fallbacks to re-reading the whole mbox file whenever something in mbox isn't
-# how it's expected to be. The only real downside to this setting is that if

-#
-# For the sql passdb module, you'll need a database with a table that
-# contains fields for at least the username and password. If you want to
-# use the user@domain syntax, you might want to have a separate domain
-# field as well.
-#
-# If your users all have the same uig/gid, and have predictable home
-# directories, you can use the static userdb module to generate the home
-# dir based on the username and domain. In this case, you won't need fields
-# for home, uid, or gid in the database.
-#
-# If you prefer to use the sql userdb module, you'll want to add fields
-# for home, uid, and gid. Here is an example table:
-#
-# CREATE TABLE users (
-#     username VARCHAR(128) NOT NULL,
-#     domain VARCHAR(128) NOT NULL,
-#     password VARCHAR(64) NOT NULL,
-#     home VARCHAR(255) NOT NULL,
-#     uid INTEGER NOT NULL,
-#     gid INTEGER NOT NULL,
-#     active CHAR(1) DEFAULT 'Y' NOT NULL
-# );
-
-# Database driver: mysql, pgsql, sqlite
-#driver =
-
-# Database connection string. This is driver-specific setting.
-#
-# HA / round-robin load-balancing is supported by giving multiple host
-# settings, like: host=sql1.host.org host=sql2.host.org
-#
-# pgsql:
-#   For available options, see the PostgreSQL documention for the
-#   PQconnectdb function of libpq.
-#   Use maxconns=n (default 5) to change how many connections Dovecot can
-#   create to pgsql.
-#
-# mysql:
-#   Basic options emulate PostgreSQL option names:
-#     host, port, user, password, dbname
-#
-#   But also adds some new settings:
-#     client_flags        - See MySQL manual
-#     ssl_ca, ssl_ca_path - Set either one or both to enable SSL
-#     ssl_cert, ssl_key   - For sending client-side certificates to server
-#     ssl_cipher          - Set minimum allowed cipher security (default: HIGH)
-#     option_file         - Read options from the given file instead of
-#                           the default my.cnf location
-#     option_group        - Read options from the given group (default: client)
-#
-#   You can connect to UNIX sockets by using host: host=/var/run/mysql.sock
-#   Note that currently you can't use spaces in parameters.
-#
-# sqlite:
-#   The path to the database file.
-#
-# Examples:
-#   connect = host=192.168.1.1 dbname=users
-#   connect = host=sql.example.com dbname=virtual user=virtual password=blarg
-#   connect = /etc/dovecot/authdb.sqlite
-#
-#connect =
-
-# Default password scheme.
-#
-# List of supported schemes is in
-# http://wiki2.dovecot.org/Authentication/PasswordSchemes
-#
-#default_pass_scheme = MD5
-
-# passdb query to retrieve the password. It can return fields:
-#   password - The user's password. This field must be returned.
-#   user - user@domain from the database. Needed with case-insensitive lookups.
-#   username and domain - An alternative way to represent the "user" field.
-#
-# The "user" field is often necessary with case-insensitive lookups to avoid
-# e.g. "name" and "nAme" logins creating two different mail directories. If
-# your user and domain names are in separate fields, you can return "username"
-# and "domain" fields instead of "user".
-#
-# The query can also return other fields which have a special meaning, see
-# http://wiki2.dovecot.org/PasswordDatabase/ExtraFields
-#
-# Commonly used available substitutions (see http://wiki2.dovecot.org/Variables
-# for full list):
-#   %u = entire user@domain
-#   %n = user part of user@domain
-#   %d = domain part of user@domain
-#
-# Note that these can be used only as input to SQL query. If the query outputs
-# any of these substitutions, they're not touched. Otherwise it would be
-# difficult to have eg. usernames containing '%' characters.
-#
-# Example:
-#   password_query = SELECT userid AS user, pw AS password \
-#     FROM users WHERE userid = '%u' AND active = 'Y'
-#
-#password_query = \
-#  SELECT username, domain, password \
-#  FROM users WHERE username = '%n' AND domain = '%d'
-
-# userdb query to retrieve the user information. It can return fields:
-#   uid - System UID (overrides mail_uid setting)
-#   gid - System GID (overrides mail_gid setting)
-#   home - Home directory
-#   mail - Mail location (overrides mail_location setting)
-#
-# None of these are strictly required. If you use a single UID and GID, and
-# home or mail directory fits to a template string, you could use userdb static
-# instead. For a list of all fields that can be returned, see
-# http://wiki2.dovecot.org/UserDatabase/ExtraFields
-#
-# Examples:
-#   user_query = SELECT home, uid, gid FROM users WHERE userid = '%u'
-#   user_query = SELECT dir AS home, user AS uid, group AS gid FROM users where userid = '%u'
-#   user_query = SELECT home, 501 AS uid, 501 AS gid FROM users WHERE userid = '%u'
-#
-#user_query = \
-#  SELECT home, uid, gid \
-#  FROM users WHERE username = '%n' AND domain = '%d'
-
-# If you wish to avoid two SQL lookups (passdb + userdb), you can use
-# userdb prefetch instead of userdb sql in dovecot.conf. In that case you'll
-# also have to return userdb fields in password_query prefixed with "userdb_"
-# string. For example:
-#password_query = \
-#  SELECT userid AS user, password, \
-#    home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \
-#  FROM users WHERE userid = '%u'
-
-# Query to get a list of all usernames.
-#iterate_query = SELECT username AS user FROM users
