multi-pack-index: store local property

A pack-file is 'local' if it is stored within the usual object directory. If it is stored in an alternate, it is non-local. Pack-files are stored using a 'pack_local' member in the packed_git struct. Add a similar 'local' member to the multi_pack_index struct and 'local' parameters to the methods that load and prepare multi- pack-indexes.
