Bug#948212: sage-maxima.lisp isn't found correctly

[Julien Puydt]

Package: sagemath
Version: 8.9-3

Running "import sage" in Python 3 works, but probably only because of
some lazy loading ; indeed:

>>> from sage import *

In Debian we really have that file in /usr/share/sagemath/bin, so I
guess it's just a path to patch away.
