[Pkg-privacy-maintainers] Bug#975533: mat2's autopkg tests fail with Python 3.9

[nicoo]

Hi,

There doesn't seem to be anyone else handling the mat2 RC bug (FTBFS &
autopkgtest failure) so I will do it.

AFAICT this is only a matter of importing the right upstream commit
(62ec8f6c1efc06364eb5f8c3d81e1b5dbcfc6e64) as a Debian patch.


Best,

  nicoo
