Fix issue with concatenating $dmarc_milter and $dkim_milter in main.cf (#3380)

Browse source 
* Fix issue with concatenating $dmarc_milter and $dkim_milter in main.cf 

Upon each start the  `smtpd_milters` and `non_smtpd_milters` would be extended with the following:
```
smtpd_milters =   $dmarc_milter $dkim_milter
non_smtpd_milters = $dkim_milter
```
In my case they became long enough that mail delivery stopped. I think this was because of the extra headers that are added by these steps. (which in turn would cause the mail to be dropped)

* fix sed to work when the variables are there and when they are not.
