mpich: wrapperrpath variant allows disablement of RPATH usage in mpicc

Browse Source 
Added a wrapperrpath variant to mpich that defaults to `True`.

Users can set this to `False` (e.g., spack install mpich~wrapperrpath) to
disable the wrapper RPATHs.  This makes it easier to replacing an MPICH
installation in a container with an MPICH for the host system,
e.g., Cray MPICH with Shifter on Cori, Intel MPI, MVAPICH2, etc.
