Debian only introduced tomli in the bookworm release. Use a vendored wheel to avoid requiring a package that is only in bullseye-backports and is also absent in Ubuntu 20.04. While at it, fix an issue in the vendor.py scripts which does not add a newline after each package and hash. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
