To make sure bug on XFS is detected on systems which use it.

Due setgid is test problematic on Microsoft filesystems:

creat09.c:81: TBROK: ntfs: Setgid bit not set
creat09.c:76: TBROK: chown(exfat,65533,4) failed: EPERM (1)
creat09.c:76: TBROK: chown(vfat,65533,4) failed: EPERM (1)

thus they're disabled.

Changes v1->v2:
* drop useless code creating directory (reported by Martin Doucha)

This can be removed.

Is this new include still needed?

Agreed, either make WORKDIR relative to MNTPOINT and use chdir
or add "/" and then chdir can be dropped.

True, since mntpoint implies tmpdir. But for readability I'd keep it,
it makes it
more visible that cwd is tmpdir at start of test.
