GTP: fix parsing of GTP headers (#1161)
Message length checks and basic headers are not uniform across GTP-U,
GTP-C and GTP-PRIME.
Note that, even if the length checks were wrong, the GTP sessions were almost
always correctly classified because of the "guessing" algorithm.
This patch has been tested with GTP-U, GTP-C-V1, GTP-C-V2 and GPT-PRIME-V2
traffic using ndpiReader with "-d" flag (to avoid "guessing" algorithm) and
without "-t" flag (to avoid GTP-U de-tunneling).
See #1148
