libosmosim: class_tables: Resolve conflicting CLA=8x INS=F2 definitions
In their infinite wisdom, GlobalPlatform re-defined the CLA 8x / INS F2 command
alreay specified by ETSI TS 102 221. This wouldn't be as bads if they
had the same "Case". However, ETSI has case 2 while GP has case 4.
Lucikly, the P1 coding of ETSI [so far] states all the four upper bits
must be 0, while GP always has one of those bits set.
Before this patch, it is possible that a Modem/Phone will send an 8xF2
command and intends it as a GlobalPlatform command (with Lc > 0 and
command data portion), while this code assumes it is an ETSI UICC
command with Lc=0 and hence no command data portion. This will make
communication break when using simtrace2 'cardem'.
