And this broke building applications in Flatpak. The udev API isn't
stable, so cannot be used in sandboxed applications where the system
version of the daemon might not match our expectations.

This commit along with changes in gnome-nightly-apps should get us over
the hurdle in the short-term.

    pnp-ids: Add --disable-udev command-line argument
    
    This will allow building gnome-desktop in environments where libudev
    isn't available (such as flatpak's Sdk) until we have a thumbnailing API
    living in the platform API (likely GLib or GTK+).
