The BPF sample sockmap is redundant now that equivelant tests exist
in the BPF selftests. Lets remove this sample and only keep the
selftest version that will be run as part of the selftest suite.

While building samples/sockmap, undefined reference error is thrown

This program binds a program to a cgroup and then matches hard
coded IP addresses and adds these to a sockmap.
This will receive messages from the backend and send them to
the client.
client:X <---> frontend:10000 client:X <---> backend:10001
To keep things simple this is only designed for 1:1 connections
using hard coded values. A more complete example would allow many
backends and clients.
To run,
# sockmap <cgroup2_dir>
