fallback: fix lid switch event listener being initialized twice
Once the lid is closed, the keyboard event listener is set up to open the lid
for us on keyboard events. With the right sequence, we can trigger the
listener to be added to the list multiple times, triggering an assert in the
list test code (or an infinite loop in the 1.8 branch).
Conditions:
* SW_LID value 1 - sets up the keyboard listener
* keyboard event - sets lid_is_closed to false
* SW_LID value 0 - is ignored because we're already open
* SW_LID value 1 - sets up the keyboard listener again
