libgimp: further cleanup in GimpGradientChooser code.

Browse source 
- No need of local_grad_data_new(). Just set default variables in init()
  as it should be.
- Also move gimp_gradient_chooser_draw_interior() to the init()
  function, so that the new() function is only a wrapper of
  g_object_new() which is the proper way to implement new classes.
- Get rid of wrong comment.
