We do have specific tests that examine the outputs of rebuilding the
indices (all the fuzzer group tests do this too); this patch enables a
test runner to expand that coverage to all tests.  Running a
rebuilding xfs_repair for all the tests shook out some bugs in the
xfs_repair rmap handling code that only triggered under some of the
non-rmap non-reflink stressor tests.
