scd: New option to APDU command to return the ATR as data.

Browse source 
* scd/command.c (cmd_apdu): Add new option --data-atr.
* tools/gpg-card.c (cmd_apdu): Use that here.  Also fix the --exlen
option and do not print the statusword in atr mode.
* tools/card-call-scd.c (scd_apdu): Detect atr mode anddon't assume a
status word.
