Hide mac background mode prefs ui if background mode is not enabled.

Change to Preferences.xib: Setup preferences_window_controller.mm as a referencing outlet for the background mode UI so we can hide it.

BUG=53522
TEST=run chrome without --enable-background-mode, make sure associated prefs UI is not shown
