Databases connected via Unix domain sockets aren't well supported

[klausbrunner]

The current logic in docker-entrypoint.sh to build ROUNDCUBEMAIL_DSNW will always add ":portnumber" to the string. This doesn't work when the "host" is actually a Unix domain socket specification of the form "unix(/var/bla/sockets)", as the resulting connection string is invalid.

My current workaround is to add an overriding configuration PHP file that redefines $config['db_dsnw']. Works, but it's a bit of a hack.

Suggestion: don't add the colon + port number unless one is explicitly passed in. The default should be fine in most cases anyway. Of course, wait_for_it.sh can't be used the same way then.

Same, I'm using the HOST and PORT on the ENV vars and overriding it on the config file too...
