[pmg-devel] [PATCH pmg-api] pmgsync.service: order before postfix at .service

pmgsync.service updates the database-schema (pmgdb init) and generates and
updates configuration files from the templates and reloads the respective

When first booting up after installation, it adapts the config from what's
shipped in the default debian packages for the first time.

The postfix configuration is also rendered, including settings where a
restart is necessary (listening on the internal port (26)).

While the unit already starts before postfix.service, the postfix service
files are designed to start multiple instances of postfix via instantiation
(by default postfix at -.service is the single instance (and the service file
which actually starts postfix)).

Since both pmgsync and postfix at - have no ordering relation between them, they
are started in parallel, which leads to postfix starting with the stock config
upon first boot.

Tested by running the installer in debug mode and applying this patch in the
last debug shell.
