ddns-scripts: get public_suffix_list.dat without using secure connection

Get public_suffix_list.dat without using secure connection. #3678

File generated during build, because it's the only option to have an
actual version packaged.
Long term Cloudflare_v1 package will be changed to no longer need
public_suffix_list.dat
