This uses os.Hostname, falling back on a UUID if for some reason it can't be looked up. This should work on VMs and CloudRun instances. Fixes transparency-dev#699.

Whichever is last wins. Previously we used the env variables as the base, and then the binary would replace them. This way around is more user-first: if the user is strongly opinionated that in their telemetry they want, e.g. service name to be something different, they can do.
