Umask is problematic for Go programs as it affects other goroutines (see [1] for more details). Instead of using it, let's just prop up with Chmod. Note this patch misses the MkdirAll call in createDeviceNode. Since the runtime spec does not say anything about creating intermediary directories for device nodes, let's assume that doing it via mkdir with the current umask set is sufficient (if not, we have to reimplement MkdirAll from scratch, with added call to os.Chmod).
