input: kitty keyboard modifier event changes from Kitty 0.32

Browse Source 
> When the key event is related to an actual modifier key, the corresponding
> modifier's bit must be set to the modifier state including the effect for the
> current event. For example, when pressing the :kbd:`LEFT_CONTROL` key, the
> ``ctrl`` bit must be set and when releasing it, it must be reset. When both
> left and right control keys are pressed and one is released, the release event
> must have the ``ctrl`` bit set. See :iss:`6913` for discussion of this design.
