Title: costmap_2d: export library layers

Many layer plugins also instantiate a FootprintLayer. Layers created outside the costmap_2d package were not able to link against liblayers. The outside layers would still compile, but loading an outside layer before a layer in costmap_2d caused a plugin load error.
