The main problem is that "check-venv" is a .PHONY target will always
evaluate and trigger a full re-build of the VM images. While its
tempting to drop it from the dependencies that does introduce a
breakage on freshly configured builds.
Fortunately we do have the otherwise redundant --force flag for the
script which up until now was always on. If we make the usage of
--force conditional on dependencies other than check-venv triggering
the update we can avoid the costly rebuild and still run cleanly on a
fresh checkout.
