Series fstests: fixes for realtime rmap | expand

Commit Message

Darrick J. Wong Dec. 30, 2022, 10:20 p.m. UTC 
From: Darrick J. Wong <djwong@kernel.org>

The realtime rmap tests were added to fstests a long time ago.  Since
they were added, we decided to create a metadata file directory
structure instead of adding more fields to the superblock.  Therefore,
fix all the tests that try to access these paths.

While we're at it, fix xfs/409 to run the *online* scrub program like
it's supposed to.  xfs/408 is the fuzzer for xfs_repair testing.
