 mpi portgroup: Improve enforce_variants for depspec; move checks to
 configure and archivefetch.

 Use of mpi.enforce_variant could be done with a depspec rather than a port
 name (e.g. path:/opt/local/lib/libplumedKernel.dylib:plumed) but the
 resulting error messages were not clear; now it will give the name of an
 actual port in messages. The pre-fetch checks on dependencies should be
 done in pre-configure since only then are the dependencies guaranteed to
 be installed; a similar check should be done in pre-archivefetch for
 binaries. (Similar to https://trac.macports.org/ticket/54890 for compilers
 portgroup.)
