Instead of always skeletonizing MPI calls, skeletonize those MPI calls that operate on null variables only. Instead of specifying pragma sst keep to turn off skeletonization have a pragma pragma sst nullmpi to turn off payloads to the MPI call.

Related: Several MPI collectives are missing from the auto-skeletonization check list (such as gather)
