k3s: add services, missing binaries.

- Fix version string in 'k3s -v' output to match release builds.

- Adds the missing hyperkube binary. This conflicts with kubernetes, so
  it may be an issue for folks who want to install both k3s and
  kubernetes at the same time. Not sure who those folks are, but
  I guess it could be a subpackage too.

- Fixes k3s builds to include kubectl and crictl (previous revisions
  included the CLI commands in the usage output but could not be used).

- Add service files for k3s-agent and k3s-server.

- Fetch Traefik manifests for codegen bits of the build.

- Update short_desc to match k3s description.

- Set homepage to k3s.io.

Closes: #15101 [via git-merge-pr]
