1) Fail if we can't read critical env vars 2) Don't rely on KUBE_ROOT env var when `go list` works 3) Don't rely on GOOS env var when `go env` works 4) Don't quietly ignore "can't read" errors Once we stop ignoring errors, some tests fail for real (and should always have failed). The "Imported k8s.io/staging constant" test seems to not be allowed at all anymore. Han said to nix it and he'd look async. Oversall this test is dodgy. You REALLY can't glue strings together and expect valid Go module paths. We should consider a deeper rework.
