In order to be able to write a multi-pack index during repacking, `git repack` must keep track of which packs it wants to write into the MIDX. This set is the union of existing packs which will not be deleted, new pack(s) generated as a result of the repack, and .keep packs. Prior to this patch, `git repack` populated the list of existing packs only when repacking all-into-one (i.e., with `-A` or `-a`), but we will soon need to know this list when repacking when writing a MIDX without a-i-o. Populate the list of existing packs unconditionally, and guard removing packs from that list only when repacking a-i-o. Additionally, keep track of filenames of kept packs separately, since this, too, will be used in an upcoming patch.
