  Shutdown when triggering daemon-reload eary in boot

Bug description:
  In Ubuntu Core 20, and Ubuntu Core 22, we are encountering an issue
  where if a service, started earlier than devices are processed by
  udev, does `systemctl daemon-reload`, the system shuts down. This is
  due to devices for mounted filesystem temporarily taken dead, which
  pulls most units down.

  This was fixed by upstream in
  https://github.com/systemd/systemd/pull/23218.

  But this was not backported to the versions used by Ubuntu packages
  for focal and jammy. The needed commit from that PR is the one with
  message `core/device: ignore DEVICE_FOUND_UDEV bit on switching root`.

  This patch applies to 245.4-4ubuntu3.22 (focal) without rebasing
  needed. And I suppose it does also for jammy.

  I have manually tested the fix with Ubuntu Core 20, and this fixes our
  issue.

  We would like this patch to be backported to focal-updates and jammy-
  updates.

  Thank you in advance.
