debounce lid events

The patch remove the event before adding it anew. It applies against 1.8.3
which is the version I tested against (debian sid).

This fixes the issue that the same event is inserted twice into the list. That
we then ends up with a list item that points to itself.

I also safeguards the removal of this event listener by this
keyboard_is_monitored flag.

The flag tells we already attached this keyboard listener so that even if the
state is_closed is not switched yet we avoid duplicates.
