systemvm: serve cloud-domain and cloud-domain-id from their own metadata files

The latest/cloud-domain and latest/cloud-domain-id rewrite rules on the
virtual router pointed at the vm-id file, so both returned the VM id
instead of the domain name and domain id. The latest/meta-data/cloud-domain
paths were not affected.
