keyboard_scan: Send kb events at start of debouncing period.
Current behavior is to start a timer upon first detecting a transition of
any one cell of the keyboard matrix, and then generate a keyboard event
(press or release) only after that timer has expired. Due to the fact that
the release timer has a longer period than the press timer, in some cases,
e.g. releasing the shift key right before depressing another key, events
could end up getting re-ordered.
