        [WPE][GTK] Another memory issue in xdgmime

        https://bugs.webkit.org/show_bug.cgi?id=187239

        Reviewed by NOBODY (OOPS!).

        Sync the end of xdg_mime_get_mime_type_for_file() with _xdg_mime_cache_get_mime_type_for_file()

        to avoid a memory issue.

        I'm pretty sure this code is never executed by either Chromium or WebKit, but I'm not

        comfortable with leaving it broken.
