Fix wdired handling of symlinks when restoring filename property

* lisp/wdired.el (wdired--restore-dired-filename-prop): Use
dired-permission-flags-regexp instead of dired-filename to test
whether the file is a symlink, since calling file-symlink-p on the
latter may fail in wdired-mode (bug#32673).
