Debian: Adjust temp fix for /etc/platform.conf

Now that kickstarts are enabled, adjust the early workaround generating
the contents of /etc/platform/platform.conf.

This needs to be fully removed after fixing the openstack-dashboard
package.

Test Plan:
PASS - Build ISO
PASS - Install ISO
PASS - Run Ansible bootstrap
