duneci-standard-tests: OpenMPI: allow oversubscription, force degraded mode

# Allow oversubscription (tests might want to try having more ranks

# than environment has processors) and force degraded mode (as we

# might run multiple tests in parallel and this is not good with

# OpenMPI's agressive mode)
