more setuptools breakage

[totaam]

python3-cryptography not installing correctly.

This is caused by yet another setuptools update breaking something, which also caused some other problems: https://github.com/Xpra-org/xpra/commit/351c05fb67b5f811ff41dbfdeae471243822c8b1

The ugly solutions are:

cd /Users/macos/gtk/source/cryptography-36.0.1
cp ./build/lib.macosx-10.12-x86_64-3.9/cryptography/hazmat/bindings/_openssl.abi3.so ../cryptography-36.0.1/build/temp.macosx-10.12-x86_64-3.9/build/temp.macosx-10.12-x86_64-3.9/_openssl.o /Users/macos/gtk/inst/lib/python3.9/site-packages/cryptography/hazmat/bindings/
cp ./build/lib.macosx-10.12-x86_64-3.9/cryptography/hazmat/bindings/_openssl.abi3.so $JHBUILD_PREFIX/lib/python3.9/site-packages/cryptography/hazmat/bindings/

And:

python3 ./setup.py install --old-and-unmanageable

Things were perfectly manageable until setuptools started breaking things twice a day.

I see no way of telling distutils to use the compatibility flag: https://gitlab.gnome.org/GNOME/jhbuild/-/blob/master/jhbuild/modtypes/distutils.py

This also affects bcrypt and breaks paramiko.

Perhaps we can patch the command directly and revert the default?

Many more issues recorded in #25 - but at least now we can build from scratch..
