I should have pushed the branch to GitLab first:

  https://gitlab.com/abologna/libvirt/-/pipelines/185421025

We might be able to adopt a more nuanced approach, where we use
ws_version.h where available and fall back to config.h where it's the
only option, but I'm not quite sure how to implement that in Meson
