After we have packed all refs, we prune any loose refs that
correspond to what we packed. We do so by first taking a
lock with lock_ref_sha1, and then deleting the loose ref
file.
However, lock_ref_sha1 will refuse to take a lock on any
refs that exist at the top-level of the "refs/" directory,
and we skip pruning the ref. This is almost certainly not
what we want to happen here. The criteria to be pruned
should not differ from that to be packed; if a ref makes it
to prune_ref, it's because we want it both packed and
pruned (if there are refs you do not want to be packed, they
should be omitted much earlier by pack_ref_is_possible,
which we do in this case if --all is not given).
We can fix this by switching to lock_any_ref_for_update.
This behaves exactly the same with the exception of this
top-level check.
