config: meta: also save the QEMU version installed during creation

This is intended to be used to apply some workarounds for the
non-windows ostyped VMs which we'd still like to not pin on a
specific machine version, as normally Linux et al. can cope with such
changes on fresh boot just fine and until now this was a once every
few year issue (albeit systemd's "predictable" interface naming has
some potential to pick up on churn frequency).
