[Freeciv-Dev] (PR#4585) bug in center_tile_overviewcanvas

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

PR#4561 had a bug in it - center_tile_overviewcanvas is passed the 
center tile not the origin of the mapview, so we don't have to add back 
on the radius of the mapview.

Because the math is off, the overview doesn't center on the correct 
location (although it still behaves sanely).
