Upstream linbox 1.2.2 should need this patch

But it is not yet enough because the sage matrix interface was changed
from "jagged pointers" to a single sequential vector.
I believe I could make a patch for `sage/libs/linbox/linbox.{pxd,pyx}` but
I do not feel confident about other places where sage interfaces to linbox
matrices.
