EclCpGridManager: disable parallelism (for now)

Browse Source 
this is because the loadBalance() method of Dune::CpGrid is seriously
broken at the moment: it throws away elements even in sequential mode
for some more relevant grids. ("more relevant" == "Norne". Norne is is
buggy itself because it features two completely disjoint parts.)

but it is even worse than that: if the bug mentioned above bites,
Dune::CpGrid cannot even agree for itself how many elements it has
which causes the CartesianIndexMapper to segfault.
