[petsc-dev] testing code which use partitioners

[Jed Brown]

METIS will use its internal implementation if USE_GKRAND is defined.
Maybe other partitioners have similar functionality.

I'm not wild about the complexity of providing our own definitions.
Note that libmetis.so does not link to libpetsc.so so it would be
nontrivial to make that work with both shared and static libraries.
