gprs/test: Add additional gbproxy tests

This adds a test case with several messages to test BSSGP patching.
New messages:

- BSSGP/DTAP Attach Request
- BSSGP/DTAP Attach Accept
- BSSGP/DTAP Routing Area Update Request
- BSSGP/DTAP Routing Area Update Accept
- BSSGP/DTAP Activate PDP Context Request
- BSSGP SUSPEND
- BSSGP SUSPEND ACK
