fix deadlock on AndroidMap<>Viewport:

Browse Source 
- on GL-Thread:
MapRenderer.draw()->MapAnimator->update()->AndroidMap.updateMap
                    [sync: Viewport       [sync: AndroidMap ]]
- on Mainloop:
AndroidMap.redrawMapInternal()->updateLayers()->Viewport.getMapPosition()
[sync:AndroidMap                               [sync:Viewport]]

... no need to sync on AndroidMap
