From: Chao Yu <yuchao0@xxxxxxxxxx>
After fsync, filesystem should guarantee inode metadata including
i_flags being persisted, so even after sudden power-cut, during
mount, we should recover i_flags fields correctly, in order to not
loss those meta info.
So adding this testcase to check whether generic filesystem can
guarantee that.
We only check below attribute modification which most filesystem
supports:
- no atime updates (A)
- secure deletion (s)
- synchronous updates (S)
- undeletable (u)

v2:
- add missing _require_chattr
- use $CHATTR_PROG/$LSATTR_PROG
- add -f parameter for rm
- cleanup codes of traversing each parameter for chattr
