iotests: Add quorum case to test 110 

Test 110 tests relative backing filenames for complex BDS trees.  Now
that the originally supposedly failing test passes, let us add a new
failing test: Quorum can never work automatically (without detecting
whether all child nodes have the same base directory, but that would be
rather inconsistent behavior).
