Increase timeout for waiting for physical interfaces to show up

200ms does not seem to be enough for our test infra. There have been test failures where tethering test was started on devices with physical interfaces that were available for tethering (i.e. cuttlefish on Android R and S).

This change increases the timeout to 1000ms, which unfortunately means the tests will take a bit longer.
