parse/cache/cooker: Preserve order in the file inclusion list

The data returned by get_file_depends() may me used in contexts like
checksums where order is important. The current usage of sets means
that some of the checksums can change in circumstances they should not.

This patch changes to use lists, thereby removing the problem.
