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. Closes-bug: #2051859 Change-Id: I2a59f4eb3ae27f37fda38e05924315887cb04c41 (cherry picked from commit 3942d29448d16b4ef8e9682b4d08fd03d1dbe2cd)
