- Addendum to r24421: get mca_maffinity_libnuma to compile on linux

(with libnuma-2.0.4 / LIBNUMA_API_VERSION 2): numa_get_run_node_mask
   returns a struct bitmask *.

   Whether it's a good idea to blindly pass that on to
   numa_set_membind() is another matter: one might want to match against
   the list returned by numa_get_mems_allowed(), which may be set by the
   outside environment.

   Refs trac:2698.
