Fixes the input images replacement for the initial layers of the fedora-coreos image

[aleskandro]

Hi @LorbusChris, the fedora-coreos image is based on the processed Dockerfile.template from the layering-build image (Dockerfile.ci)...

I see that Dockerfile.template essentially rebuilds the image okd-rpms in the third stage based on two layers (the artifacts and machine-config-operator tags) that are not replaced by the prow config...

IIUC, we may want to either change the lines 1-9 of the okd-machine-os' Dockerfile.template to be FROM registry.ci.openshift.org/origin/4.12:okd-rpms AS rpms or the prow config for the fedora-coreos image as in this PR. Or is it a wanted behavior?

Refers #31663

Right, we'll want to get rid of that

[aleskandro]

Ok, so should I close this one?

[vrutkovs]

Yeah, I think so. We want to extract MCO binary from okd-rpms, so that it would the single source of RPMs and binaries

[aleskandro]

Ok, thanks @vrutkovs ... Closing
