Meson.build script isn't properly detect mpich as MPI impl.,
therefore meson option 'custom-mpi' is used now with export
of CC=mpicc and CXX=mpicxx as compilers.
Mpi implementations is restricted with MPI 3.1 within ebuild.
FEATURES="-network-sandbox" could be required to run tests
for some mpi implementations/versions.
