multi-pack-index: store local property

Browse Source 
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.
