sensors/VehicleAngularVelocity: fix force SensorSelectionUpdate

- This fixes the force call on SensorSelectionUpdate
 - In contrary to the rest of the codebase, this method also takes a timestamp: When you call SensorSelectionUpdate(true), time_now_us is actually set to 1 and force stays false, as this is the default value for in the method.
