Remove fbpseudocolor

"An experimental pseudocolor emulation layer.  Not fully completed,
currently only works for 16bpp."  That was almost four years ago.
It still doesn't work, only one driver even attempts to use it, it
contains an ad-hoc implementation of damage, and should really be
done up in Composite now anyway.
