[LTP] [PATCH] Fix ioctl_ficlone on XFS without reflink support

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

reflink has been introduced in XFS by kernel 4.9 and mkfs.xfs enabled
by default in 5.1.0. Check the mkfs.xfs version in order to make sure
that mkfs.xfs supports reflink and verify kernel is at least 4.9 when
we run the ioctl_ficlone tests on XFS.

Signed-off-by: Andrea Cervesato <andrea.cervesato@suse.com>
---
ioctl_ficlone tests are failing in certain circumstances. In particular,
when kernel version is lower than 4.9 and mkfs.xfs is not 5.1.0
