gvr's Arm model apparently does not take into account the user's head position
on 6DoF systems, leaving the arm model "locked" in place near the origin. This
change manually offsets the controller model by the head's position so that the
arm model for the controller stays at a constant relative position to the head.
This yields behavior that matches Google's other first-party VR applications.
