LU-18048 tests: skip sanityn test_16j unaligned DIO

sanityn.sh test_16j was failing often in cases where the client
was running an older version than the server because of
changes that were made on master from LU-13805. This started with
generic testing but added UDIO-specific options in later patches so
an interop check has been added to avoid failing the test on older
versions.
