generic/673: Add separate sgid stripping sub-tests
Even kernel doesn't get ATTR_KILL_SGID mask and get ATTR_KILL_SUID mask,
we still can strip S_ISGID mode in setattr_prepare and setattr_copy.
We should check separate sgid stripping logic whether works well
on different filesystems.
Also fix comments error.
