[LTP] [PATCH v2 1/1] creat09: Run on all_filesystems

[Petr Vorel]

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.

* drop useless code creating directory (reported by Martin Doucha)
