Add a new ioctl to vt to make it possible to export RGB offsets set by vt drivers. This is needed to fix colors on X and Mesa on some machines, especially on modern PowerPC64 BE ones. With the appropriate changes in SCFB, to use this ioctl to find out the correct RGB offsets, this fixes wrong colors on Talos II and Blackbird, when used with their built-in video cards.
