Dovecot: make home dir distinct from mail dir (#3335)

* add new home dir for Dovecot

I tried changing the mail dir, but this is a _very_ disruptive change,
so I took approach 3 on
<https://doc.dovecot.org/configuration_manual/home_directories_for_virtual_users/>,
whereby the home directory is now inside the mail directory.

The MDBOX/SDBOX formats are not touched by this change. The change
itself could be considered breaking though.

* adjust Sieve tests accordingly

* Update target/dovecot/10-mail.conf

* Update target/dovecot/auth-passwdfile.inc
