auto-update: clarify systemd-unit requirements
Clarify in the help message and the man page that auto updates only work with systemd units that are similar to the ones from `generate systemd --new`. Units that merely start/stop a container do not work as they will use the same image. Fixes: #6793 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
