t5319: expand test data

As we build the multi-pack-index file format, we want to test the format
on real repositories. Add tests that create repository data including
multiple packfiles with both version 1 and version 2 formats.

The current 'git multi-pack-index write' command will always write the
same file with no "real" data. This will be expanded in future commits,
along with the test expectations.
