Remove the mentions of the native OSX wxListCtrl control

This control was removed during the Carbon code removal in commit
5ba67c67e4, so the system option
does nothing now (and was only mentioned in the documentation
and the sample).

-    <b>wxMac Note</b>: Starting with wxWidgets 2.8, wxListCtrl uses a native
-    implementation for report mode, and uses a generic implementation for other
-    modes. You can use the generic implementation for report mode as well by setting
-    the @c mac.listctrl.always_use_generic system option (see wxSystemOptions) to 1.
+    @note The native wxOSX implementation for report mode that was added in wxWidgets
+    2.8 was removed in wxWidgets 3.1, meaning for wxWidgets 3.1+ wxOSX uses the generic
