workflows: Remove rootfs binary artifacts

We need the publish certain artefacts for the rootfs,
like the agent, guest-components, pause bundle etc
as they are consumed in the `build-asset-rootfs` step.
However after this point they aren't needed and probably
shouldn't be included in the overall kata tarball, so delete
them once they aren't needed any more to avoid them
being included.

Fixes: #10575
