Fix T42919 & T42218: BGE: Python-driven armature animation got buggy

Due to changes in the way animation updates were handled,
BL_ArmatureObjects were no longer registering to KX_Scene as animated.

Moguri says: It might have been relying on the deformer update which
moved rom being called on every object in the render step. Now
armature deformers are only updated if they need to be.
