midx: teach "git multi-pack-index repack" honor "git repack" configurations
When the "repack" subcommand of "git multi-pack-index" command creates new packfile(s), it does not call the "git repack" command but instead directly calls the "git pack-objects" command, and the configuration variables meant for the "git repack" command, like "repack.usedaeltabaseoffset", are ignored. Check the configuration variables used by "git repack" ourselves in "git multi-index-pack" and pass the corresponding options to underlying "git pack-objects". Note that `repack.writeBitmaps` configuration is ignored, as the pack bitmap facility is useful only with a single packfile.
