Patchset:

PS1: this needs testing first. I tried to tst via pySim, but even with firmware prior to this change, it seems like my version of pcsc-lite is patching the 4byte TPDU already, so we need a lowl-level CCID test case to actually verify this. But then eclipse-titan for debian unstable is currently not instlalable anymore, so I'm blocked by that.
