Remove broken pusher delta yaw manipulation. 

This didn't work correctly for multiple reasons:

1. `deltayaw` was wrongly initialized for the pusher itself, rather than
for pushed client.

2. `delta_angles[YAW]` is a short, adding plain `amove[YAW]` to it is
wrong.

To support yaw angle rotation properly, delta_angles must be
interpolated on the client. But this is hardly practical as it would
introduce other bugs. Thus, simply remove delta yaw manipulation code
altogether.

Fixes infamous Q2 bug when player standing on a blocked lift gets turned
to wrong direction.
