Subject: [PATCH] wireguard: selftests: tie socket waiting to target pid
commit 88f404a9b1d75388225b1c67b6dd327cb2182777 upstream.
Without this, we wind up proceeding too early sometimes when the
previous process has just used the same listening port. So, we tie the
listening socket query to the specific pid we're interested in.
