[vtkusers] vtkPoissonReconstruction problem in Release mode

[David Gobbi]

Set the WRAP_EXCLUDE property for all files that don't start with "vtk".

SET_SOURCE_FILES_PROPERTIES(
  Factor.cpp Geometry.cpp MarchingCubes.cpp
  MultiGridOctest.cpp MultiGridOctreeData.cpp
  WRAP_EXCLUDE)

The vtkPoissonReconstructionFilter is the only class you need to see
from python, so all the rest can be excluded from the wrapping (but
they still need to be in the SRCS because they need to be linked into
the library).
