auto-update service: prune images

Extend the systemd auto-update service to prune images after an update
has run.  As reported by a user [1], auto updates can over time cause
the disk to run out of space.  With Edge being a target use case, we
need to make sure that systems can run without much supervision, so
let's make sure to run `podman image prune` to clean up dangling images.
