t5319-multi-pack-index.sh: test batch size zero

The 'git multi-pack-index repack' command can take a batch size of
zero, which creates a new pack-file containing all objects in the
multi-pack-index. The first 'repack' command will create one new
pack-file, and an 'expire' command after that will delete the old
pack-files, as they no longer contain any referenced objects in the
multi-pack-index.

We must remove the .keep file that was added in the previous test
in order to expire that pack-file.

Also test that a 'repack' will do nothing if there is only one
pack-file.
