        Add paths for egg-info files for an external egg-base.

        The egg-info files are written to egg-base. If egg-base is
        outside the current working directory, this method
        searchs the egg-base directory for files to include
        in the manifest. Uses distutils.filelist.findall (which is
        really the version monkeypatched in by setuptools/__init__.py)
        to perform the search.

        Since findall records relative paths, prefix the returned
        paths with cmd.egg_base, so add_default's include_pattern call
        (which is looking for the absolute cmd.egg_info) will match
        them.
