bpftool can do all the things load_sock_ops used to do, and more.
Point users to bpftool instead of maintaining this sample utility.

The program was returning -1 in some cases which is not allowed
by the verifier any longer.

Sample BPF program that assumes hosts are far away (i.e. large RTTs)
and sets initial cwnd and initial receive window to 40 packets,
send and receive buffers to 1.5MB.
In practice there would be a test to insure the hosts are actually
far enough away.
