Disable code to directly call code in the tk driver if it is enabled. The octave interface for this tk code does not exist. Octave will now work again with just the plain tk driver. This must have been broken for a long time (at least since we moved to CMake) and no-one has complained so I guess this octave and tk are just not widely used.
