BpfHandler: only allow to tag udp/tcp socket

The TrafficController socket destroy listener only monitors
on the group {INET_TCP, INET_UDP, INET6_TCP, INET6_UDP}.
Tagging listener unsupported socket causes that the tag can't
be removed from tag map automatically. Eventually, the tag map
run out of space because of dead tag entries.

See TrafficController::makeSkDestroyListener in
packages/modules/Connectivity/service/native/TrafficController.cpp
