mesa/st: use unclamped colors
This assumes that Gallium is to be interpreted as given drivers the
responsibility to clamp these colors if necessary.

mesa, mesa/st: handle read color clamping properly

the operation mandates it. (see the removed XXX comment. -Marek)
TODO: did I get the set of operations mandating it right?
