Fix broken fuzz_process_packet fuzzer by adding a call to ndpi_finalize_initialization().fix/memory-errors-and-packet-fuzzer
* fixed several memory errors (heap-overflow, unitialized memory, etc)
* ability to build fuzz_process_packet with a main()
allowing to replay crash data generated with fuzz_process_packet
by LLVMs libfuzzer
* temporarily disable fuzzing if `tests/do.sh`
executed with env FUZZY_TESTING_ENABLED=1
