There's a bug, the ustat() sysetm call is not implemented on someone
arch, but xfsprogs uses this to detect whether a filesystem is
mounted in platform_check_ismounted() function.

If ustat() is not implemented, platform_check_ismounted() return
"isn't mounted" if a filesystem is mounted, that's a big problem, it
will cause corruption.

Hi,

Thanks Eryu and Eric helped to review V1 patch, this V2 patch did below things:
1. Add more comments for every sub-tests
2. change the xfs/group file, remove "mount" group, and add some other groups
3. modify some typo errors

Please feel free to correct me, if you find anything wrong. I've tested this
case on (x86_64) RHEL-7.2, RHEL-6.8 and upstream kernel+xfsprogs, all passed.

Thanks,
Zorro
