Stop replicating to local git mirror on gerrit

We've disabled access to the local gerrit git mirrors at the /p/ prefix
previously as newer gerrit uses that path for something else. The next
step is to stop replicating to that location entirely.

Another reason for this is when we switch to notedb this local
replication will replicate everything then if we expose it we'd
potentially expose content we don't want to via git (rather than the
gerrit APIs).
