Subject: [PATCH] cards: populate ADM1 key reference member

In class SimCard, we specify the key reference for ADM1 as 0x04. in the
UsimCard class, which inherits from SimCard nothing is specified, even
though ETSI TS 102 221 specifies 0x0A as key reference. Lets set the
member in UsimCard accordingly to be closer to the spec.

Note: For the moment this is a cosmetic fix, it does not change the
behaviour since all card classes derived from UsimCard set the key
reference properly.
