Remove --kept-pack-only option and associated infrastructure

This option to pack-objects/rev-list was created to improve the -A and -a
options of repack.  It was found to be lacking in that it did not provide
the ability to differentiate between local and non-local kept packs, and
found to be unnecessary since objects residing in local kept packs can be
filtered out by the --honor-pack-keep option.
