tangogps: drop at 0.99.2

tangogps is abandoned. It looks like it this is the case since the early
2010s. foxtrotgps is a fork, that still is maintained.

-      tangoGPS is an easy to use, fast and lightweight mapping
-      application for use with or without GPS.
-
-      It runs on any Linux platform from the desktop over eeePC down
-      to phones like the Openmoko Neo.
-
-      By default tangoGPS uses map data from the OpenStreetMap
-      project.  Additionally a variety of other repositories can be
-      easily added.
-
-      The maps are automagically downloaded and cached for offline use
-      while you drag or zoom the map.  Furthermore you can
-      conveniently pre-cache areas with tangoGPS.
