Subject: postfix: Add service entrypoint script

This is used to generate database files used by postfix daemons.

In theory, this could also be performed at build-time by the Dockerfile.
However, I intend to create only a single image that each service
separately spawns from, since there will be several commonalities
between them.  Moving these postfix-specific tasks to an entrypoint
script keeps the common Dockerfile more managable.
