BUG: vtkMacroKitPythonWrap: Remove unnecessary link against VTK_PYTHON_LIBRARIES

Since the variable VTK_WRAP_PYTHON_FIND_LIBS was removed in
Kitware/VTK@ed49fa01c (VTK v9.0.0) but is still used in VTK v8.2.0,
this commit conditionally set it.

Similarly it removes the link against VTK_PYTHON_LIBRARIES
as any necessary link should be picked up via the INTERFACE_LINK property
of VTK::Python.
