selftests/bpf: Test sys_connect BPF hooks with TFO
TCP Fast Open is triggered by sys_sendmsg with MSG_FASTOPEN flag for
SOCK_STREAM socket.
Even though it's sys_sendmsg, it eventually calls __inet_stream_connect
the same way sys_connect does for TCP. __inet_stream_connect, in turn,
already has BPF hooks for sys_connect.
That means TFO is already covered by BPF_CGROUP_INET{4,6}_CONNECT and
the only missing piece is selftest. The patch adds selftest for TFO.
