refactor(ops/pipelines): Move 🦆 logic into static pipeline
This simplifies the fallback logic used in case of Nix evaluation failure and makes it so that the evaluation step itself is the one that is marked as failed in Buildkite. This is possible because the pipeline upload command will insert new steps at the point where it runs in the pipeline, and not later. Change-Id: I870534c004ebc457a1602623c4e5f9c0c68e28fc
