On wakeup from suspend restore remembered keyboard brightness

Some laptops turn off keyboard backlighton their own when the lid is closed,
so when you close the lid, it will suspend and remember the turned off keyboard
backlight, and turn it back off on wake up.

This patch instead remembers the last keyboard brightness when it changes
and restores that value on wake up
