Fix more "missing on-disk files" warnings

See this job for examples. The only warnings remaining pertain to translations (which we no longer ship, because we no longer ship gettext), and a strange error regarding the librsvg license files.

The license files warning must be something really arcane, because the files exist on-disk, and the only suspect is the fact that we have a custom post_install() which does super() into the derived class, but that still breaks something.
