FileManager: Make DirectoryView open links in their real directory

Previously it was possible to open a link like /home/anon/Desktop/Home,
leading to a folder with the same name. Now it correctly opens its real
path, which is /home/anon

FileManager: Use Core::File::real_path_for to get real path of links
