fix SimCardCommands.run_gsm(): always use CLA=0xa0 

Depending on the card type (SIM or USIM/ISUM), self.cla_byte may
be either 0xa0 or 0x00.  Sending RUN GSM ALGORITHM with CLA=0x00
fails with SW=6985 (Command not allowed), so let's make sure
that we always use CLA=0xa0 regardless of the card type.
