spectrum-mpi: Add new package file for external package (#3005)

* spectrum-mpi: Add new package file for external package

IBM Spectrum MPI is a commercial implementation of MPI based on
OpenMPI.  It is usually install in /opt/ibm/spectrum_mpi.

Users need to add the Spectrum MPI package in their packages.yaml
file as follows:

packages:
    spectrum-mpi:
        version: ['10.1.0.2']
        paths:
            spectrum-mpi@10.1.0.2: /opt/ibm/spectrum_mpi/
        buildable: False

    all:
        providers:
            mpi: [spectrum-mpi@10.1.0.2]

* spectrum-mpi: Added license files and removed the versions

No need for versions as the package is external.

* spectrum-mpi: Remove extraneous defines

Keep only the defines that other MPI implementation define in their
package file:
    self.spec.mpicc
    self.spec.mpicxx
    self.spec.mpif77
    self.spec.mpifc
