`#ifdef PARMETIS_MAJOR_VERSION` used before defined

From dune/grid/utility/parmetisgridpartitioner.hh:

#if HAVE_PARMETIS

// only enable for ParMETIS because the implementation uses functions that
// are not emulated by scotch
#ifdef PARMETIS_MAJOR_VERSION

#include <parmetis.h>

But PARMETIS_MAJOR_VERSION is only provided by the #include <parmetis.h> (and this file is the only place in dune-grid where parmetis.h is included).

Does scotch also provide parmetis.h? Then the order could just be changed.
