sci-libs/parmetis: major refactoring
1. Update to EAPI 7 and cmake.eclass
2. Unbundle sci-libs/metis
3. Remove IUSE=mpi - with METIS unbundled, settings USE=-mpi effectively
turns this package into a metapackage
4. Add USE=fortran requirement to virtual/mpi - without it,
libparmetis.so ends up with unresolved symbol MPI_Comm_f2c
5. CMakeFiles are now modified by patches rather than sed - the changes
are entirely static so there is no need for the latter
