udev: Apply patches to update to version 251 and add dummies for current tags

- eudev-3.2.12 has udev version 243 and this causes the build of libgudev to fail as
   it requires a newer version of udev.
- Just changing the version in eudev from 243 to 251 is insufficient as libgudev also
   expects to see current tags which have been introduced in a more recent version of
   systemd udev.
- Two patches applied from the eudev github issue #249 covering this problem.
- With the two patches applied libgudev built without any problems.
- Update to rootfile not required.
