felixm ed5085ab6b M1: make evidence tests race-clean
Rewrite TestFakeSourceEmits to synchronize through a channel (it now
asserts emission instead of racing on a shared slice and discarding it).
Skip the live X11 smoke test under -race: xgbutil's event loop has an
internal Quit/Quitting race on shutdown that is never reached in
production (Watch runs under a never-cancelled context.Background()).
