Bug 1347815 - part3: label RuleProcessorCache::mExpirationTracker.
RuleProcessorCache::mExpirationTracker.NotifyExpired() will be invoked by
nsExpirationTracker::TimerCallback() from an unlabeled runnable.
Since RuleProcessorCache is a browser-wide cache, we provide a SystemGroup
EventTarget for the invocation of this callback.
