The copy step should be idempotent if a previous playbook run failed

[bstinsonmhk]

If a previous run of adhoc-sshd_sign_host_key.yml fails, and then the playbook is re-run, the files exist on the CA, but have not been copied yet. We should probably register a check from the target, and condition on that instead of checking if signing happened.
