Yes, we can. It might not help Sam much though because he is
interested to find out unused header file in system header files.

One way to do it is just let stream keep track of its parent and
is_toplevel.

Just add another pass inside show_unused_streams(). Mark all used
stream's parents as used.

Should be straight forward enough to implement base on branch
"unused-include-files". Any brave sparse hackers want to
give it a try?
