🐛 Work around lack of kubebuilder-tools for darwin/arm64

[mboersma]

What this PR does / why we need it:

When I run make test on my M1 Mac, I get:

% make test
unable to fetch checksum for requested version: unable fetch metadata for kubebuilder-tools-1.23.3-darwin-arm64.tar.gz -- got status "404 Not Found" from GCS
KUBEBUILDER_ASSETS="" go test ./...
<numerous test failures of course>

Overriding with the equivalent of GOARCH=amd64 works fine.

Which issue(s) this PR fixes:

N/A

Is it not possible to build them today?

We might need a PR to this branch https://github.com/kubernetes-sigs/kubebuilder/tree/tools-releases

I think this branch does not define for which GOOS/GOARCH the job is run (https://github.com/kubernetes-sigs/kubebuilder/blob/tools-releases/build/cloudbuild_tools.yaml)

But I have no idea how to find the cloud build config for that.

EDIT: Maybe it's this > https://github.com/kubernetes-sigs/kubebuilder/pull/1992/files#r573150243

kubernetes-sigs/kubebuilder#2516 merged, so hopefully the next release of kubebuilder-tools will offer a darwin/arm64 build.

I'm still a bit skeptical if the merged PR is enough, given: kubernetes-sigs/kubebuilder#2516 (comment)

I would be okay with merging this workaround + creating a follow-up issue for cleanup if that makes folk's lives easier until kubebuilder assets are available.

I would also expect that those might only be available after the next Kubernetes release. I would guess that the kubebuilder assets for the current releases are not necessarily automatically rebuild after a kubebuilder release.

+1 to get this merged and tracking cleanup as soon as artifacts are available from the kubebuilder project
