Ensure openvmm still builds the way a Linux distribution package builds
it.
This configuration does not use the repository’s .packages/
provisioning. Every native dependency comes from a distribution package,
and the uploaded vendor archive is consumed exactly the way a packager would
consume it.
The build runs against a git archive export of HEAD rather than the
checkout, both because that is the tree a packager gets from the tag source
archive and because the checkout may be a developer’s working tree.
