Only tag/untag AF_INET and AF_INET6 sockets.
Socket tagging only actually works for real network sockets, so skip
tagging all other socket families like AF_LOCAL.
For calls like accept() and close() that don't readily have family
information, use the Linux-specific SO_DOMAIN option to pull it from
the kernel. Define both SO_DOMAIN and SO_PROTOCOL for anyone to use
in the future.
Test: builds, boots, only tags internet sockets
