Valentin Rothberg db26e1ef94 auto-update: make restarted unit more obvious ...

The output of auto-update leaves quite some space for improvements.  One
thing is to make it more obvious which systemd units were restarted.

With this change, the output looks as follows:
```
$ podman auto-update

Restarted the following systemd units:
$unit-1
$unit-2
$unit-3
```
