increase initial search radius for reverse lookups

On the osm.org instance, this saves 2 psql queries for about 87% of
reverse requests consequently increasing throughput significantly. A lower
value might make sense if an instance is used only in areas with very
high mapping density but for standard usage this one should be better
suited.
