uniform: remove unnecessary uniformquat update callback
uniform: remove unnecessary uniformquat update callback

UniformQuat.value can not be animated (this is AnimatedQuat purpose),
only live changed. A live-change is the only event that can cause a
value change. Since the matrix is properly updated by
uniformquat_update_func() in case of a live-change event, the update
callback is unnecessary.
