Subject: is_{hfs,ntfs}_dotgitmodules: add tests

commit dc2d9ba3187fcd0ca8eeab9aa9ddef70cf8627a6 upstream.

This tests primarily for NTFS issues, but also adds one example of an
HFS+ issue.

Thanks go to Congyi Wu for coming up with the list of examples where
NTFS would possibly equate the filename with `.gitmodules`.
