Listen for LOCKSCREEN_USE_DOUBLE_LINE_CLOCK changes on all users

KeyguardClockSwitchController already uses USER_ALL for it's equivalent
listener. Looks like we missed this detial when writing the new code.

Also spotted a usage of LOCK_SCREEN_WEATHER_ENABLED that wouldn't update
to listen to the current user correctly.
