drop postgres module from soc defaults injection

The soc binary on 3/dev does not register a postgres module, so injecting
postgres into soc.config.server.modules makes soc abort at launch with
'Module does not exist: postgres'. The soc-side module is staged on
feature/postgres but is not landing this release. Drop the injection
until the module ships; salt/postgres state and pillars are unchanged.
