The `.variables` sets `CGO_ENABLED=1` on arm; b0c41b78d8/scripts/build/.variables (L57-L68)
And if enabled, it sets `-buildmode=pie`; b0c41b78d8/scripts/build/.variables (L79-L88)
But that looks to be conflicting with the hardcoded `CGO_ENABLED=0` in
this script, which causes the build to fail on go1.22;

0.135 -buildmode=pie requires external (cgo) linking, but cgo is not enabled
This patch sets the CGO_ENABLED variable before sourcing `.variables`,
so that other variables which are conditionally set are handled correctly.

When building on Fedora 36, the build failed. I suspect this is because the
rpm tools also set LDFLAGS, but with options that cannot be used;

This patch changes the variable we use to `GO_LDFLAGS`, taking a similar approach
as containerd, and various other projects using this name: https://grep.app/search?q=GO_LDFLAGS

Keeping the dockerfiles/Dockerfile.cross image at 1.13, as we don't
have more current versions of that image. However, I don't think it's
still used, so we should remove it.

To help with this add a bad plugin which produces invalid metadata and arrange
for it to be built in the e2e container.

That is, the helper to be used from the plugin's `main`.
Also add a `helloworld` plugin example and build integration.
