Tests on real hardware showed that with useGPIO=True, that is on
Raspberry hardware, the recognizing state and busy state cannot
call GPIO because the module is never imported.
Fix this by loading the module if possible, without erroring out.
We already report whether we support GPIO or not.
The actual calls to GPIO functions are already protected by useGPIO
so no further changes are necessary.
