sgsn+pcu: Port suspend/resume cases to new BSSGP_CT:GLOBAL port

For 12+ days, suspend/resume related SGSN + PCU TTCN3 tets have been failing.

It was the introduction of the BSSGP_CT:GLOBAL test port in
I40d973d80709f5d56f59247e8647b52754f09bc8 +
I805372f3024a0ec2491a24422e02c0bc6dc669d2 which caused the related PDUs
now to no longer show up where they used to.

Change-Id: I1977302fef4868dc1c330bc6f48f6a6608949393
Closes: OS#4902
