The "symbolic" parameter no longer means anything.

Removed.  This removes a test for hard linking, but it will be restored when
hard links are provided by the Link class.

-  var args = [ symbolic ? '-s' : '', dst, link ];
-  var script = 'tests/standalone/io/ln.sh';
-  if (!new File(script).existsSync()) {
-    script = '../$script';
-  }
-  Process.run(script, args).then((result) {
-    if (result.exitCode == 0) {
-      callback();
-    } else {
-      throw new Exception('link creation failed');
-    }
-  });
+  new Link(link).create(dst, linkRelative: true).then((_) => callback());
 }
