Python interface is not installed with 4.4.0+dfsg-4build1

[Pushkar Kulkarni]

With 4.4.0+dfsg-4build1, autopkgtest regressions are reported on amd64, arm64 and ppc64el (e.g amd64 [1]).
The four test failures are 'ModuleNotFoundError`s.

On dumping contents of python3-siconos_4.4.0+dfsg-4build1_amd64.deb I don't find the Python interface files being installed:

----

$ dpkg -c python3-siconos_4.4.0+dfsg-4build1_amd64.deb | grep "\.py$"
$

They can be found in the previously published package:

Found this in the build log, right after swig finishes generating the Python interface:

numpy.distutils was only deprecated previously, causing the previous build to install the Python bindings
