object-store: move struct packed_git into "packfile.h"

The "object-store.h" header contains the definition of `struct
packed_git`. As this structure hosts all kind of information about a
specific packfile it is arguably a bit out of place in a generic place
like "object-store.h".

Move the structure as well as `pack_map_entry_cmp()` into "packfile.h".
