Add native sdk class extentions to ros-distro.inc

          **{common} Add native sdk class extentions**

This looks like the correct, simple solution for now. In the longer term, we may want to replace this with a variable in ros-distro.inc that automatically extends the recipes to include nativesdk if the recipe name is in the list.
