Subject: [PATCH] install: Make Debian install fully non-interactive

Although the installation instructions specify `apt-get -y ...`, the
installation blocks when trying to install the Kata pages with a message
like this:

```
...

Restart services during package upgrades without asking?

<Yes>                                          <No>
```

Setting `DEBIAN_FRONTEND=noninteractive` avoids this.

Fixes #363.
