Start RHCOS arch jobs earlier

Basically the downside of this is that any failure related to building artifacts or testing the live artifacts will now happen after we've already forked off the other arches. Which means that instead of getting one failure in the pipeline, we'll get four.

SGTM if you want to try this, but it's a trade-off, and we might decide to toggle it back off or refine it (so that it's only enabled e.g. once we're past a certain milestone).

This also relates to openshift/enhancements#1637. A big part of the churn are the OpenShift packages, and it's going to be much cheaper to rebuild just the OCP layer on top.
