checkout test: better case-insensitive test on Mac

Browse Source 
On Mac OS, `realpath` is deficient in determining the actual filename
on-disk as it will simply provide the string you gave it if that file
exists, instead of returning the filename as it exists.  Instead we
must read the directory entries for the parent directory to get the
canonical filename.
