[gegl] Initialize babl in gegl_cl_init

    Initialize babl in gegl_cl_init
    
    The initialization of openCL creates Babl types, so babl needs to be initialized.
    This made the gobject introspection scanner crash because gegl_processor_class_init
    triggered this codepath, and babl was not initialized.
