Setting the security label file attribute fails due to the default mount
option implied by fstests:
MOUNT_OPTIONS -- -o context=system_u:object_r:root_t:s0 /dev/sdb /mnt/scratch
See commit 3839d299 ("xfstests: mount xfs with a context when selinux is on")
fstests by default mount test and scratch devices with forced SELinux
context to get rid of the additional file attributes when SELinux is
enabled. When a test mounts additional devices from the pool, it may need
to honor this option to keep on par. Otherwise failures may be expected.
Moreover this test is perfectly fine labeling the files so let's just
disable the forced context for this one.
