Title:
  makekdump should re-exec with cio_ignore on s390x

Status in Ubuntu on IBM z Systems:
  Fix Released
Status in makedumpfile package in Ubuntu:
  Fix Released

Bug description:
  As per
  https://bugs.launchpad.net/ubuntu/+source/makedumpfile/+bug/1564475/comments/19

  We should re-exec with cio_ignore lines. As per report there, it
  should result in lowered required crashdump setting.

  Hypothetically, one should be able to test this imperially by lowering
  crashdump memory settings until kdump does not succeed anymore. And
  then generated and append `cio_ignore -k -u` to the
  KDUMP_CMDLINE_APPEND= and see that kdump starts working again with a
  lower memory usage.

  Once this is developed / verified / tested, we should probably SRU
  this back to xenial.
