packaging/tools: Add kata-debug

kata-debug is a tool that is used as part of the Kata Containers CI to gather
information from the node, in order to help debugging issues with Kata
Containers.

As one can imagine, this can be expanded and used outside of the CI context,
and any contribution back to the script is very much welcome.

The resulting container is stored at the [Kata Containers quay.io
space](https://quay.io/repository/kata-containers/kata-debug) and can
be used as shown below:
```sh
kubectl debug $NODE_NAME -it --image=quay.io/kata-containers/kata-debug:latest
```

Fixes: #7397
