Merge #15013: test: Avoid race in p2p_timeouts

fabcd64 test: Avoid racy test p2p_timeouts (MarcoFalke)

Pull request description:

  Avoid filesystem/network racyness by sleeping another second. The alternative would be to poll the `debug.log`, but that seems overkill to avoid a sleep in a test that already requires them.
