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.
