puppetmaster: add GeoLite to geoip, fix for Labs

Add the new geoip::data::lite class to the puppetmaster, so that GeoLite
databases are fetched and made available to hosts as well.

While at it, remove the proprietary databases from the Labs
puppetmaster, so we can be sure they won't be made available by mistake
to public instances.
