[libvirt] [jenkins-ci PATCH v2 1/8] lcitool: Generate the unattended script file

Let's always generate the unattended script file as, by doing this, we can treat the files we have as templates, being able to change them accordingly to whatever is needed by specific distros. It's important to note that we *must* be careful and keep generating those files using their "expected" filename, preferably using the same name of the template, as some of the distros require that.
