mdadm: merge 4.2~rc2-2 from Debian unstable

This bug was fixed in the package mdadm - 4.2~rc2-2ubuntu1

---------------
mdadm (4.2~rc2-2ubuntu1) impish; urgency=medium

  * Merge from Debian unstable (LP: #1940096), remaining changes:
    - Ship finalrd hook.
    - Do not install mdadm-shutdown.service on Ubuntu.
    - Drop broken and unused init scripts in favor of native systemd units,
      which can cause failure to reconfigure mdadm package under certain
      confiment types.
    - Drop /etc/cron.d/mdadm and migrate to systemd mdcheck_start|continue
      timer units.
    - Drop /etc/cron.daily/mdadm and migrate to system mdmonitor-oneshot
      timer unit.
    - mdcheck_start.timer configures the mdcheck on a first sunday of the
      month, with a randomized start delay of up to 24h, and runs for at
      most 6h. mdcheck_continue.timer kicks off daily, with a randomized
      start delay of up to 12h, and continues mdcheck for at most 6h.
    - mdmonitor-oneshot.timer runs daily, with a randomized start delay of
      up to 24h.
    - One can use systemd drop-ins to change .timer units timings, set
      environmental variables to decrease/increase the length of checking,
      or start the checks by hand. Previously used checkarray is still
      available, albeit not used by timer units.
    - Above ensures that previous daily / monthly checks are performed, but
      are randomized, such that performance is not as impacted across a
      cluster of machines.
    - Honor the debconf daily autoscan setting in the systemd timer.
    - d/p/mdcheck-fix-empty-spaces-in-timer-unit-files.patch:
      - The spaces were causing a FTBFS situation, triggered by
        dh_installsystemd not finding units.
    - Mention mdmonitor-oneshot.service instead of /etc/cron.daily/mdadm
      in /etc/default/mdadm
