Nit: This test makes it appear as though the file paths in `results` are
starting from the same directory as the directories in owners, but actually
we're expecting the file paths to be relative to the repository root, right? By
changing the example, this could potentially be made clearer, and potentially
better-test the functionality in generate_email_list.

I think that for MockHost, with MockSCM
(https://cs.chromium.org/chromium/src/third_party/WebKit/Tools/Scripts/webkitp...),
the root of the repository may be /mock-checkout/, and the layout test dir may
be /mock-checkout/third_party/WebKit/LayoutTests/.
