autofs: upgrade 5.0.5 -> 5.0.8

* upstream: patches have been moved into the patches-5.0.x directory
* disable autofs preparing and then moving mount points

  "With the introduction of systemd the root filesystem is now usually
  marked as shared instead of private as part of the systemd sandbox
  functionality. As a consequence moving a mount from one mount point to
  another is not allowed."
