keybindings: Fix ungrabbing of keys
XUngrabKey() doesn't work for XI2 grabs and XI2 doesn't provide API with similar functionality. As such, we have to refactor the code a bit to be able to call XIUngrabKeycode() for each key binding, then reload keybindings and finally grab the new ones. https://bugzilla.gnome.org/show_bug.cgi?id=697003
