[PATCH 2 of 4] Add an override to Octave's find() for permutation matric

Because of find()'s count-limiting and direction arguments, this is
slightly more complicated than just copying the permutation vector.

I suspect this is a common operation for people who don't know about
the 'vector' option to lu().
