Commander: make RC override multicopter only

AAs discussed in the devcall this functionality is only useful for
rotary-wing (multicopter) flying since it's a big safety hazard to
accidentally bring a fixed wing out of an auto mode e.g. a mission
and fly away in a straight line or into an obstacle.
