bpf: add selftest for tcpbpf Added a selftest for tcpbpf (sock_ops) that checks that the appropriate callbacks occured and that it can access tcp_sock fields and that their values are correct. Run with command: ./test_tcpbpf_user Adding the flag "-d" will show why it did not pass.

selftests/bpf: Test case for BPF_SOCK_OPS_TCP_LISTEN_CB Cover new TCP-BPF callback in test_tcpbpf: when listen() is called on socket, set BPF_SOCK_OPS_STATE_CB_FLAG so that BPF_SOCK_OPS_STATE_CB callback can be called on future state transition, and when such a transition happens (TCP_LISTEN -> TCP_CLOSE), track it in the map and verify it in user space later.
