cc_resolv_conf: introduce tests and stabilise output across Python versions (#251)

This is a follow-up to #144 which fixed the rendering behaviour.

While writing the tests, CI failed due to dict iteration differences across Python versions, so this also sorts output so that we will produce the same output across Python versions.
