PCU: introduce TC_egprs_pkt_chan_req_reject_emergency 

At the moment, the IUT does not support any emergency services.
Make sure that EGPRS Packet Channel Request for an emergency call
is properly rejected (RR Immediate Assignment Reject).

Note that at the time of writing this test, the IUT does not
handle EGPRS Packet Channel Request properly, so it fails.
