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.
