Remove unused robot_radius parameter

@mikeferguson can you confirm this? Looking at the code and experimenting without it, it seems this parameter is unused. Perhaps this was made redundant by the `robot_radius` parameter now in [Costmap2D.cfg](https://github.com/ros-planning/navigation/blob/88e802d89a28d5dbee0ce10ab3c0ab1931830e30/costmap_2d/cfg/Costmap2D.cfg#L20).
