cephadm-adopt: fix orch host add with FQDN

When a node is configured with FQDN as the hostname value then the
`ceph orch host add` command will fail because the `ansible_hostname` used
by that command contains the short hostname which won't match the current
hostname (FQDN)
Instead we can use the ansible_nodename fact.
