World map is broken on HTTPS

[maedox]

Problem description

Loading OpenStreetMap tiles fails because their TLS certificate CN doesn't match URL's used by Graylog: https://a.tile.osm.org/1/0/0.png

Replacing osm with openstreetmap in the URL works: https://a.tile.openstreetmap.org/1/0/0.png

This isn't strictly a Graylog issue, though, so do with it what you will.

Steps to reproduce the problem

1. Access Graylog via HTTPS (I am using Apache2 as a reverse proxy).
2. Enable geo-location processor.
3. View world map for some message containing geo-location.
