Strictly require libudev if udev_sync is used.
This prevents some confusion when libudev was not found so udev_sync was disabled automatically. Configure was successful though giving only a tiny warning. Also, if "dmsetup udevcreatecookie" is used, never return 0x000000 as a result if udev is not running and keep the output blank.
