ART-18724: Pin imagebuilder to v1.2.20 for ci-openshift-build-root (4.19)

[joepvd]

Summary

Pin imagebuilder to v1.2.20 in both RHEL 8 and RHEL 9 ci-openshift-build-root Dockerfiles.

Failing builds: ci-openshift-build-root-extra.rhel8, ci-openshift-build-root-extra.rhel9, ci-openshift-build-root-latest.rhel8, ci-openshift-build-root-latest.rhel9

Analysis

imagebuilder@latest resolves to v1.2.21 which requires Go >= 1.25.5. The build environment has Go 1.24.13 with GOTOOLCHAIN=local, causing the build to fail:

go: github.com/openshift/imagebuilder@v1.2.21 requires go >= 1.25.5 (running go 1.24.13; GOTOOLCHAIN=local)

This affects all 4 ci-openshift-build-root images (extra.rhel8, extra.rhel9, latest.rhel8, latest.rhel9) across all architectures.

Changes

• ci_images/rhel-8/ci-openshift-build-root/Dockerfile: Pin imagebuilder@latest to imagebuilder@v1.2.20
• ci_images/rhel-9/ci-openshift-build-root/Dockerfile: Pin imagebuilder@latest to imagebuilder@v1.2.20

Same fix as #10492 (4.16).

Fixes: ART-18724, ART-18723, ART-18722, ART-18721
