Fix Fl_RGB_Image::uncache() and Fl_Bitmap::uncache().

Browse Source 
It is not possible to use fl_graphics_driver in these functions
because when they are called *fl_graphics_driver may have been
deleted. A solution is to use  Fl_Display_Device::display_device()->driver()
instead which is always valid.
