  2. lua.d/intel_mpi.lua: revert SLURM_ env settings 

    Now that wrexecd provides PMI-1 wire protocol, these SLURM_
environment variables (discussed in flux-framework#630) are no longer required.

  3. lua.d/intel_mpi.lua: override I_MPI_PMI_LIBRARY 

    Set I_MPI_PMI_LIBRARY to point the the Flux PMI library only
if it is set.  It works either way:  if set, the Flux PMI library
PMI-1 wire protocol client speaks with PMI-1 process manager service
in wrexecd.  If unset, Intel MPI's built-in PMI wire protocol client
speaks directly with wrexecd.

Fixes flux-framework#630
