Initialize ndpi_workflow_init context only once.

On a quite old notebook, before:

$ ./fuzz/fuzz_ndpi_reader -max_total_time="${MAX_TOTAL_TIME:-360}" -print_pcs=1 -workers="${FUZZY_WORKERS:-0}" -jobs="${FUZZY_JOBS:-0}" ./tests/pcap/
[...]
Done 3256 runs in 361 second(s)

after:

Done 5032771 runs in 361 second(s)   <----------- ~1400X

oss-fuzz will be happy!
