[PATCH] xfstests: make sure tests check for loop device support

[Brian Foster]

Several tests happen to make use of loop device support without the
requisite pre-test checks. This results in spurious failures for systems
that might not have loop device support. Add _require_loop checks to
shared/298, xfs/206 and xfs/259.
