Provide unique hostname to CSD script
Provide unique hostname to CSD script

We see failures when DNS gives us a different IP address and the CSD
trojan ends up talking to a different host to the one we're actually
trying to authenticate to. Since we use pinned certificate hashes, it
shouldn't matter that we lose the hostname and can't validate the cert
against it.
