[libvirt PATCH v3 02/10] remote: push logic for default netcat binary into common helper

[Daniel P. Berrangé <berrange@xxxxxxxxxx>]

We don't want to repeat the choice of default netcat binary setting in
three different places. This will also make it possible to do better
error reporting in the helper.
