fix the keybind handling in rootston.

As mentioned in https://github.com/swaywm/wlroots/issues/393 keybinds
did't trigger / were checked with "odd" keys and modifiers.

This commit sends the keycode through two paths, one to get the keycode
and modifiers *after* xkb handles them, a secondary path to get a "raw"
keysym without modifiers and then add the modifiers rootston knows
about.

This will result in the `[Alt]+[Shift]+2` combination I mention earlier
going through the keybind detection twice.
  1) `[Alt]+[at]`
  2) `[Alt]+[Shift]+2`

When either combination is found, the appropriate keybind is executed.
The xkb handled version will be prefered over the "raw" version.
