simtrace2-cardem-pcsc: mark reset events in GSMTAP trace

At the moment only APDUs are logged to GSMTAP. It is not uncommon that a
card is resetted by the UE multiple times during normal operation. When
the trace lacks the reset events (ATR) it becomes difficult to follow in
which state the card actually is. Let't mark reset events by sending the
ATR via GSMTAP (like simtrace2_sniff already does it)
