app/internal/xkb: fix duplicate edit events for special keys

Edit events were being sent twice, once upon key press and again on key release for special keys such as Enter, Arrow keys etc, which resulted in duplicate inputs while pressing these keys. key.EditEvents for special keys now fire once on key press only.
