Script sources are no longer parsed into sources:, but now under config:

The script sources found in fd.o are not supported by buildstream, so therefore they needed to be moved to the correct location in the bst files. This location is by overriding the build-commands under config:.This is done by default for all parsed modules, but there are also extra checks in place to now allow the catching of sources such as script, which then allows for the content inside the source to parsed and written correctly

Closes #7 (closed)
