I'm not sure what's the expected behavior from CIFS on atime/noatime, so
I added linux-cifs list for input.

If CIFS behaves similarly to NFS, looks like that you could simply add
another check for cifs in _require_atime(), as what we already do for
nfs, so all tests that _require_atime() will _notrun on cifs.

Anyway, failing the test when "noatime" mount fails is one of the
purposes of the test, and it shouldn't be removed, as we've already made
sure current FSTYP supports atime/noatime (by _require rules), so a
noatime mount failure indicates a bug in the filesystem.
