LU-5338 tests: sanity-lfsck 11b allow larger last_id

In sanity-lfsck test_11b allow the OST to report the last_id
larger than the previously-used OID on the MDS.  This may
happen if the OST preallocates additional objects or skips
some objects during recovery.

Add wait_update_cond() and wait_update_facet_cond() to
allow checking an arbitrary condition against the expected
result rather than only exactly equal to the expected value.

Remove the wait_result() helper function, which is essentially
the same thing as wait_update_facet(), and only has a few users.
