pack-objects: consider packs in multi-pack-index
When running 'git pack-objects --local', we want to avoid packing
objects that are in an alternate. Currently, we check for these
objects using the packed_git_mru list, which excludes the pack-files
covered by a multi-pack-index.
Add a new iteration over the multi-pack-indexes to find these
copies and mark them as unwanted.
