Harald Welte f3f2e25864 gbproxy: Use separate NS-VC for data / signalling on SGSN side 
As we know, many production deployments have SGSN architectures with
clear control / user plane split.  In such situations, IP-SNS of the
SGSN informs us of two (classes of) IP endpoints:

    some that have control_weight > 0 and data_weight 0
    some that have control_weight 0 and data_weight > 0

Let's adjust the GBProxy_Tests.ttcn to use such a configuration for
each of the two simulated SGSNs.

Closes: OS#4953
