Check for job_supports_mpi() inside MPI Allgather functions.

MPI calls are only allowed if MPI_Init has been called. To simplify
calls to MPI::sum, MPI::max etc. and avoid putting job_supports_mpi()
around them, place this hopefully very cheap test inside the functions.

Also moved job_supports_mpi() from the namespace Utilities::System to
Utilities::MPI.
