Move /usr/share/scanservjs to /var/lib

Closes #695

This is, unfortunately, a breaking change. But it's worth doing sooner rather than later.

Run the following after installing the new version

```sh
sudo mv -v /usr/share/scanservjs/* /var/lib/scanservjs/
sudo rm -rfv /usr/share/scanservjs
```

It will report an error for the preview directory, but that's fine.
