stp: Add TC_ipa_to_m3ua_ni()
This tests sets a non-zero default network-indicator in the ss7 instance and then performs an IPA -> M3UA translation while checking if the M3UA side now uses the specified default network-indicator (NATIONAL). Change-Id: Id4f9d0ff67e114a119ab032d44ac0dfd34f5c402 Related: SYS#5421
