[LTP] [PATCH v6 2/2] syscalls/utimensat01: "chattr" command error

[Cui B. <cui...@hu...>]

The "chattr" command in case failed in some file system(such as memory fs):
'chattr: Inappropriate ioctl for device while reading flags on'

I learn that chattr command only can be used in ext2 or ext3 (ext4 is ok now).
So we check it before running.
