Bug#943831: should recommend xz-utils

[Tomas Pospisek <tpo_deb@sourcepole.ch>]

Package: python3-apt
Version: 1.8.4
Severity: normal
Tags: patch

Please add `Recommends: xz-utils`. I happended to stumble into the same
problem as reported here: https://github.com/geerlingguy/docker-ubuntu1804-ansible/issues/7

The solution recommended there is to install `xz-utils`. After
installing `xz-utils` I can report that the `ansible` playbook run
succeeded.

I am thus assuming that `ansible-playbook` depends on `python3-apt` on the remote machine,
which apparently depends on `xz-utils` to manipulate or manage `*.deb`
packages.

Is my analysis correct? If so then please add the `Recommends: xz-utils`
dependency.
