Returns C<($path, $stow_path, $package)> where C<$path> and
C<$stow_path> are relative from the top-level target directory.
C<$path> is the full relative path to the member of the package
pointed to by C<$link_dest>; C<$stow_path> is the relative path to the
stow directory; and C<$package> is the name of the package; or C<('',
'', '')> if link is not owned by stow.
Returns C<($pkg_path_from_cwd, $stow_path, $package)> where
C<$pkg_path_from_cwd> and C<$stow_path> are relative from the
top-level target directory. C<$pkg_path_from_cwd> is the full
relative path to the member of the package pointed to by
C<$link_dest>; C<$stow_path> is the relative path to the stow
directory; and C<$package> is the name of the package; or C<('', '',

cwd must be the top-level target directory, otherwise
C<find_containing_marked_stow_dir()> won't work. Allow for stow dir
