Neels Hofmeyr 8df7d15a66 sgsn: test GMM Attach with 3-digit leading-zero MNC 
Add general infrastructure to
- pass an MCC-MNC for BSSGP to use into f_init();
- verify that the Attach Accept PLMN matches the BSSGP one.

Add TC_attach_mnc3() to feed an MNC with three digits and a leading zero, to
verify the recent mnc3 patches. When testing against a libosmocore and
osmo-sgsn before mnc3, this results in:

Test case TC_attach_mnc3 finished. Verdict: fail reason: "mismatching PLMN in Attach Accept: 02342F; expected 023042"

With the current master branches the proper 3-digit MNC with leading zero is
fed back into the Attach Accept message.
