Jorge, could you please double-check the focal test? I couldn't get it
to pass here with the updated package, and I tried twice in a different
focal container:

Jammy and kinetic passed fine. Focal is the one with the different
patch...

  Failure to get free disk space breaks "rabbitmqctl status" command

Bug description:
  [Impact]

  When for some reason the df command fails to get the disk free space
  (for example timeout on a heavily loaded system) the result is a
  harcoded value of "unknown". As this is not a valid number this
  generates arithmetic errors when the "rabbitmqctl status" command is
  run and tries to divide that value to convert it to another unit.

  This has been fixed upstream here:
  https://github.com/rabbitmq/rabbitmq-server/pull/4897

  [Test Plan]

  The df command can be linked to another file that just waits for a few
  minutes to force a timeout for example: [detailed steps in comment
  #5].

  #!/bin/bash
  sleep 5m

  After the timeout occurs the "rabbitmqctl status" returns an error
  with the unpatched version. After the patch it shows all the
  information and displays unknown in the free space line.

  [Where problems could occur]

  The patch just changes the display of information, it should not break
  anything in the core operations of the package
