Ensure lock on suspend and unlock on resume
This patch is adopted from xfce4-screensaver: https://git.xfce.org/apps/xfce4-screensaver/commit/?id=9e53bb2866 Modified to match screen locking behavior of mate-power-manager. Introduced new Inhibitor lock to make sure lock was in place and user will be greeted with unlock dialog when resumes from suspend/ hibernate.
