tree-wide: introduce PYTHON_SETUP_ARGS to customize setup.py calls on Debian

Browse source 
On Debian the `distutils` module is patched, so `get_python_lib()`
returns by default `/usr/lib/python3/dist-packages` (no minor version)

But `setuptools` affecting setup.py is not patched to create the library
directory at `/usr/lib/python3/dist-packages` by default, rather than a
command line argument `--install-layout deb` is added

Add PYTHON_SETUP_ARGS as argument to affected setup.py calls and add a
note in the global README.md

See https://www.debian.org/doc/packaging-manuals/python-policy/packaging_tools.html
Section B.1

make DESTDIR=~/obj install install-rubywrap install-pywrap
On Debian `PYTHON_SETUP_ARGS=--install-layout=deb` needs to be set when installing the python wrappers in order to create the correct python directory structure.
To run tests with the built libraries and programs, several paths (relative to `$DESTDIR`) need to be added to variables `$LD_LIBRARY_PATH`, `$PATH` and `$PYTHONPATH`.
This can be done using [./scripts/env_use_destdir](./scripts/env_use_destdir):
