avoid 64bit overflow in Partiioner::set_ghost_indices

We MPI::sum() a 32 bit value of the total number of ghost indices, which
might overflow. This is unlikely to be a problem unless you exactly have
2^32 ghost indices, but this is nevertheless a bug.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
