Properly generate systemUiVisibilityChanged callbacks. 

User activity is supposed to immediately revert
HIDE_NAVIGATION, but we were just showing the navigation bar
directly. By routing through the service we'll generate
callbacks for everyone.

At long last, SYSTEM_UI_FLAG_HIDE_NAVIGATION will work like
lights out (now called SYSTEM_UI_FLAG_LOW_PROFILE) which
worked well enough in Honeycomb.
