Title: mavlink: Only sending HIL control commands if the system is actually armed

This fixes confusing results in HIL when the system is outputting actuator controls when the system is actually disarmed and some of the other onboard logic is not initialized properly / still in a disarmed state. This ensures the HIL experience is the same as in the field.
