wmaker: Marked args as unused for compiler in XClickEvent callback code

The toolkit dispatches X events for MouseButton using callback functions,
which means having a fixed argument list for that function.

It is then correct to not use all the arguments, so this patch adds the
appropriate stuff to avoid a false report from compiler.
