gnu: openmpi: Remove references to compiler pathnames in "_info" programs. 

This reduces the closure greatly, but note that the Fortran .mod files are
gfortran version-specific, so there should probably be development packages
for each incompatible version.  (The runtime is supposed to be more-or-less
version-independent unless the libgfortran soname changes.)  There may still
be a case for a separate runtime output.

* gnu/packages/mpi.scm (openmpi)[arguments]: Add "remove-absolute" phase.
