Libguestfs - Sep 2019 - [PATCH] builder: templates: set "unassigned" hostname

By default the installer will set the hostname to what the DHCP returns,
exposing details of the machine where make-template.ml runs.

Instead, force "unassigned-hostname.unassigned-domain" as hostname, so
plays nicely with the hostname setting code in virt-customize.

Yes, good idea, ACK.

I've been trying to build a CentOS 8 image for a couple of days,
so far without success ...
