refactor(ops/modules): Move cgit configuration into a module r/3836

The ancient `//web/cgit-taz` path stems from the time I had
code.tazj.in serving my initial version of the depot.

I've been meaning to clean this up for forever, so here we go.

Note that this leaves the git-serving module in a strange state where
it only deals with josh. I'll rename it accordingly.
