bscnat: Introduce test TC_ctrl_location
It checks location-state TRAP is forwaded correctly in BSC-NAT from BSC towards locally connected CTRL client, with variable names updated to contain BSC/BTS indexes. It also verifies commands can be applied (SET) in inverse direction. Change-Id: If28aba011a1903788cacbc10c0b62954925d4b1f
