on whitby, cgit runs as the gerrit user to get access to serving
gerrit's repositories directly.
on other machines (e.g. sanduny) this isn't necessary, as we have a
world-readable depot replica.

It occured to me yesterday that with the config inside of the module
it is kind of difficult to test cgit locally.
This moves it back to a separate location (//web/cgit-tvl) and makes
the most important things configurable via overrides.
