Fix up remove Wakeup preferences

Follow the bug fix addressed in http://review.cyanogenmod.org/#/c/43544/

This fix the issue both Home key wake and Volume rocker wake preferences will be displayed
if either of them activated in device config.

If both of them are not activated it looks fine because eventually Wakeup category
itself removed,though.

Add lockscreen rotation as an optional rotation setting (2/2)

This will allow the user to select wether or not to use the
rotation settings for the lockscreen.  This is dependent
upon the rotation setting being checked.
