graphics/wings: update to 2.2.4 and unbreak

wing's own Makefiles do make some unlucky assumptions (like that the
top directory was named "wings" without any version), which requires
some rather ugly cleanups from our side. As the command line of the
erlang runtime has changed since "back in the days", I'm fixing the
wrapper script as well.
