tests: avoid losing trace2 socket readiness signal

The trace2 socket test uses a Condition to wait for its server to start
listening. If the server calls notify() before the test starts waiting,
the notification is lost and the test waits for the full 120-second
timeout before continuing.

Use an Event for the readiness signal instead.
Once the server starts listening, the event stays set, so the test can
continue immediately even if the server becomes ready before the test
starts waiting.
