Freeze break request: fixing race condition breakage for pkgdb_sync

Any +1s?
Explanation in the commit message.

Note: we should work on improving the script in general, but that is not something we should
consider pushing during freeze, so this is a patch that hopefully gets us through the freeze.

    Make pkgdb_sync more resilient by always calling SETUP_PACKAGE if master does not exist
    This should make it recover in case there are any repos in a weird state (aka, no master branch).
    This could for example happen if the package was created in pkgdb after pkgdb_sync ran, but before
    genacls.pkgdb runs, because then gitolite will see it as a new repo, and create a totally blank repo.
    Especially since pkgdb_sync will abort after the first error, it would then leave all later created
    repos broken as well.
    Calling setup_git_package in a repo without master branch has no ill effect:
    - Running git init on a pre-initialized repo is a no-op (or at least doesn't destroy current git data)
    - Since it doesn't have master, it didn't run the script, so adding the first commit and hooks etc are
      what we want the script to do
