Public bug reported:

[Impact]
Some laptops can generate multiple rfkill events from a single key press.

[Fix]
Commit f4dbcf3d7b0f951fe44b29229206c97b625dbfda ("media-keys: Add one second 
delay between each rfkill event").
The commit adds a delay between each rkfill events to only process the first 
event and debounce the later ones.

[Test]
On HP ZBook G7, use `libinput debug-events` to observe there are two rfkill 
events on single key press. Airplane mode will be enabled and disabled in a 
very short period, so the airplane mode cannot be turned off by the hotkey 
anymore.

After applying the fix, pressing airplane mode hotkey can enable or
disable airplane mode correctly.

[Where problems could occur]
Since the delay is hardcoded as 1 second, the airplane mode cannot be switched 
on/of in a very short time anymore.
