Enable /some/ testing of online fsck for everybody by adding these two
fsstress tests and two fsx tests to the auto group. At this time I
don't have any plans to do the same for the other scrub stress tests.
Q: Can you explain why only these four?
A: The rest of the stress tests pick /one/ metadata type and race
scrub/repair of it against fsstress by invoking xfs_io repeatedly.
xfs/28[56] runs the whole xfs_scrub program repeatedly so we get to
exercise all of them in a single test.
The more specific tests make it a lot easier to debug problems.
