fix: update talos machinery pkg

This PR updates to the latest machinery pkg in the release-0.7 branch
(siderolabs/talos@bef498d). This fixes a bug where kubelet could not be found because we were generating configs that were still using docker.io as the repo.

We'll want to do this update again once a GA 0.7 release gets cut.
