www/gitlab: Make Gemfile-handling through options easier

Currently MySQL und PostgreSQL entries were removed from Gemfile
via patch and added back through options.

Now we just remove the entries of the option set to off.

This remove some work and pitfalls from the Gemfile-patch.

Thanks to sunpoet for this suggestion.
