In some cases, applications (or actually, wayland compositors) don't have the required permissions to access evdev directly, but can do so with an external helper like weston-launch. Allow them to do so with a custom callback that replaces the regular open() path. https://bugzilla.gnome.org/show_bug.cgi?id=704269
