SGSN_Tests: add missing RIM ROUTING ADDRESS field in request

When sending the RAN INFORMATION REQUEST on GTP-C, we do not add a RIM ROUTING ADDRESS + RIM ROUTING ADDRESS DISCRIMINATOR field next to the RAN TRANSPARENT CONTAINER. Those two fields are requred by the spec, see also: 3gpp TS 29.060, section 7.5.14
