sb: Add an orphan check to sb-check.

Browse Source 
The orphans check lets you see which configuration and build set
files in the RSB are not referernced. You can audit the list and
remove any configuration files not being used. Top level
build set files are included so you need to becareful not to
remove something that is valid and useful. To run:

 $ ./source-builder/sb-check --check-orphans
