Logan V c7e907794c Ensure machine-id is not included in images

Two bugs are addressed.

1) The sysprep element was broken in that it only truncates
   /etc/machine-id, but not /var/lib/dbus/machine-id. systemd will
   not generate a new machine-id if /var/lib/dbus/machine-id is
   present[1], it will simply copy it to /etc/machine-id.

   We observed machine-ids being packaged in /var/lib/dbus/machine-id
   on several distros: Ubuntu Bionic, Fedora 29, Debian Stretch.

   CentOS 7 and Ubuntu Xenial do not contain packaged machine-id as
   far as I can tell.

   All test builds were performed using -minimal elements.

2) A second bug existed where debian-minimal did not run the sysprep
   element at all, so a stretch image I tested contained a populated
   /etc/machine-id AND a populated /var/lib/dbus/machine-id.
