[libvirt] [jenkins-ci POC 2/2] guests: Add Dockerfile generator

This is basically the exact same algorithm used by the
Ansible playbooks to process package mappings, implemented
as a standalone script.
There's little to none error handling, and some information
is hardcoded instead of being configurable at runtime; more
importantly, before it can be considered for merging it
needs to be integrated into lcitool, which in turn requires
lcitool to be significantly reworked.
