Disable warnings in zoltan_cpp.h.

Without this, we get warnings of the kind
/home/bangerth/bin/trilinos-12.8.1-mpi/include/zoltan_cpp.h:181:24: warning: unused parameter ‘iperm’ [-Wunused-parameter]
                  int * iperm )
                        ^~~~~

We already do a similar thing in sparsity_tools.cc, the only other places
where we include zoltan_cpp.h.
