Remove unused code

LRU callbacks have been added in 460ff3c7a, but they have never been
used and they have never been extended to the other LRU caches.

`ndpi_search_tcp_or_udp()` basically returns the classification by port/ip
of the flow; calling it from the dissector is useless.
The same for TOR detection: ips are checked in the generic code
