Fixing the issues with {dual,quad}_flip in VTK-6.

VTK-6 algorithms only seem to work with SetInputConnection() rather
than SetInput().  These fixes may also be backwards-compatible with
VTK-5, need to check.

Change the partitioner for this test, and enable it on GCC.

For some reason, the default (Metis) partitioner partitioned this 2x2
mesh differently on Linux vs. Mac, i.e.
