RC Failsafe fix for RFD 868+/900 Modems

Browse Source 
RC Failsafe isn't triggered when PPM signal is valid. These changes
update Failsafe trigger logic for RC input. RF Modules keep sending
valid PPM signal when the RC Transmitter is lost.
RF Modules which are in the air send PPM signal with same type when lost
the signal from ground.
