Make GTP compile on its own, without LTE

Browse Source 
Avoid the include gtpv1_u_messages_types.h, as this pulls in e.g., LTE
RRC definitions. The CU-UP load tester integrated in one of the
following commits should be able to build without LTE RRC, if it was for
GTP. Unfortunately, ITTI also pulls in LTE RRC, so it's also somewhat
useless...

Put some forward declarations instead. That also shows that the API is
unnecessarily complex, and would need some cleanup.
