Rebuilder order issues

rebuilder gives the wrong output for opencolorio:

./target/release/rebuilder opencolorio
opencolorio openimageio blender krita openshadinglanguage gmic

Our graph looks as following and looks correct but has one issue, where is krita-plugin-gmic? image

Second issue, we use BFS for walking through the graph, but that does not give the right graph output for rebuilding, @felixonmars's tool reports the right order and uses a topological_sort.

$ ./genrebuild -e opencolorio
opencolorio krita krita-plugin-gmic openimageio openshadinglanguage blender
