[PATCH 06/10] xfs/{129,234,253,605}: disable metadump v1 testing with external devices

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

The metadump v1 format does not support capturing content from log
devices or realtime devices.  Hence it does not make sense to test these
scenarios.  Create predicates to decide if we want to test a particular
metadump format, then convert existing tests to check formats
explicitly.
