pkgs/build-unity: Switch to using buildGame

Now we no longer need to invoke patchelf by ourselves and all of the
dependencies are patched automatically.

I've added gtk2-x11, gdk_pixbuf and glib to buildUnity as well, because
after inspecting other Unity games they seem to require the same
libraries as well.
