Allow openmpi tests on systems with less than 4 processors

Browse Source 
The MPI tests use up to four processes.  By default, OpenMPI won't allow
more processes than processors and the tests will fail on a two
processor VM.  Using the --oversubscribe option will allow the tests to
run.

mpich doesn't have this limit by default and doesn't need or support
this option.
