[PATCH] repack: honor -d even when no new pack was created

[Martin Waitz <tali@admingilde.org>]

If all objects are reachable via an alternate object store then we
still have to remove all obsolete local packs.

Without this patch I got the following behaviour:

".git/objects/info/alternates" [Neu] 1L, 38C geschrieben

After changing git-repack, objects/pack was empty, as expected.
