xfs/078: instead file image by mkfs on loopback device
If test on 4k sector size device, xfs/078 will fail when it try to make a filesystem image with block size less than 4096. But if we attach the file image to a loop device, it can accept 512 block size. So this patch attach a loop device before do mkfs.xfs.
