clients: use wl_surface_commit

Use wl_surface_commit() to commit the buffer attach, as Weston now
requires.

NOTE: GL-applications are broken until you upgrade to a version of Mesa
which does wl_surface_commit() on eglSwapBuffers(). If you have
Cairo-gl, this means all toytoolkit apps, too.

simple-shm and simple-touch OTOH will work now.
