FlightTaskOrbit: switch rotation direction
FlightTaskOrbit: switch rotation direction

Switch to positive tangential velocity being clockwise because with NED
frame z-axis points down and mathematically positive around the z-axis
results in clockwise yaw rotation when seen from above. Also MAVLink
messages and other components in PX4 are defined this way.
