On newer versions of util-linux, the ``wipe_disks`` role was not
properly configured due to the fact that ``lsblk -J`` returns a slightly
different output than what was previously returned. Previously the
output would contain a key called ``mountpoint``, however this has been
changed to ``mountpoints``. This has now been fixed by looking at the
new key as well as the old key.
