selftests/bpf: test_progs: fix client/server race in tcp_rtt
This is the same problem I found earlier in test_sockopt_inherit:
there is a race between server thread doing accept() and client
thread doing connect(). Let's explicitly synchronize them via
pthread conditional variable.
v2:
* don't exit from server_thread without signaling condvar,
fixes possible issue where main() would wait forever (Andrii Nakryiko)
Fixes: b55873984dab ("selftests/bpf: test BPF_SOCK_OPS_RTT_CB")
