bts: Fully implement TC_pcu_data_req_{wrong_{bts,trx,ts},ts_inactive}()

The four existing test in BTS_Tests.ttcn so far didn't have any chance
to verify if the invalid messages actually ended up on the air interface
or not.  By using virtphy instead of trxcon, we can finally add that missing part.
