sim: When decoding SW, take application specific SW into account
So far we only looked at SW definitions of the card profile. However, if we have a currently selected application, we also must check that application for SW definitions. This breaks ABI and API all over the place, but as there are no known users beyond osmo-sim-test, this is acceptable. Change-Id: I3a1d60898529c173f73587e34c155660ba5f5fb1
