bts: Test if BTS forwards ETWS Primary Notification to PCU
All MS/UE must be notified of ETWS Primary Notifiations.
Depending on their state, the notification goes different paths:
* CS dedicated mode: BSC sends it as L3 message over LAPDm / DCCH
* CS/PS idle mode: BTS sends paging messages on PCH
* PS TBF active: PCU send Packet Application Info
This tests the last of the three methods by checking that a ETWS Primary
Notification sent on RSL to the BTS is received by the PCU socket.
