[LTP] [PATCH v4 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.

changes v3->v4:
* remove useless .needs_tmpdir

changes v2->v3:
* add missing dir separator /
* remove unused SAFE_CHDIR() (was needed due missing /)
* remove unused <stdio.h>
