dev-smartcard-reader: change default protocol to T=0
We don't support T=1 so we shouldn't advertise it by default. Two independent changes: * Default ATR sets T=0. This gets overwritten by the client provided ATR later. * Class descriptor changes dwAdvertise dwProtocols.PPPP to 0x1 and dwProtocols.RRRR=0 per spec.
