Log Message:
Update gnome-desktop3 to 3.24.2

- Use udev's hwdb to query PNP IDs (--disable-udev to disable this)

As we don't use udev, this is a regression, however I haven't found any
consumer of gnome_pnp_ids_get_pnp_id()

Highlights:
- Always prefer the backend-provided preview in thumbnails (#738503)
- Use ibus-libzhuyin as default input method for Simplified Chinese (#772674)
- Deprecated gnome_desktop_thumbnail_scale_down_pixbuf (#775991)
- Always use external gdk-pixbuf thumbnailer (#768064)
- Remove dependencies on xrandr and xext
- Add API to know if a GnomeRRMode is interlaced
