Add geolite-legacy 2015-03-26

The geoip package only installs a GeoIP _library_ which is useless
without a GeoIP _database_.

The only package to currently install such a database is ntopng, which
manually downloads Maxmind's GeoLite Legacy files to a private location.

Provide these as a separate package so other packages can use them as
well.
