Beat Küng 2b360bfd48 rcS: fixes for SYS_USE_IO=0
rc.io is called from 2 places in rc.interface:
- if [ $OUTPUT_MODE = io -o $OUTPUT_MODE = uavcan_esc ]:
  - 'set OUTPUT_MODE io' is only set within USE_IO=yes, so removing
    the check in rc.io has no effect.
  - in case of UAVCAN, we also want the IO for RC, now covered in the next
    case.
- Further down ('Start IO for RC input if needed.').
  This is intended to start IO for RC only, when fmu is already started.
  However the previous check '$USE_IO = yes' in rc.io prevented that.

In addition we don't start rc_input in case of $USE_IO = no.

Fixes no RC on Pixhawk 2 with SYS_USE_IO=0.
