Show wallpaper as background for WifiSetupActivity

b/62571086

Before this change, WifiSetupActivity's UI was overlaying atop whichever
Activity was below it in the task, so the user saw two Activities at the
same time. With this change, the Activity is now properly backed by the
wallpaper, and can now safely be shown atop other Activities.
