Fix hostname leakage from build host

Browse Source 
Many hosts (including the docker host) set HOSTNAME in the environment,
which means that unless the HOSTNAME is explicitly set in a 'config'
that the resulting image hostname will be the build host's hostname.

We fix that by unsetting HOSTNAME prior to reading the configs and
applying defaults.
