setup_git_package did the same check as pkgdb_sync did [1].
Also, if gitolite already came by, it will have created an update hook, which blocks us from pushing the initial commit (since gitolite has no idea who we are).
So in that case, we will just remove the update hook: gitolite will recreate it when it comes by the repo with genacls.sh.
The change to mkdir -p is just synto make it not print an error in case the directory already existed.

We already use the update hook for gitolite.
This introduces a new update hook, which merely chains the gitolite one,
and a new one to block pushes to badly named branches.
The new hook was written originally by Till Maas.
