[LTP] [PATCH] syscalls/fgetxattr02: Use loop instead of RAM disk

[Cyril Hrubis]

There are minimal systems that does not ship with RAM disk kernel module
which makes this test fail with ENXIO when we attempt to open the block
device in the test setup.

LTP depends on heavily on loop device driver already so it makes sense
to switch over to a loop device backed block device instead.
