LU-4887 tests: sanity-scrub interoperability tests with master

In the master branch, the default behaviour for lfsck_start without
"-t" specified will trigger all supported LFSCK components. And the
master branch uses new "-t scrub" for control OI scrub. The changes
will cause the old (2.5.58 or older) sanity-scrub test scripts fail
at test_9/test_11.
