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.
