Issue: 2to3 support has been removed in setuptools since version 58.0.0.

Fix: openwrt/packages#17311

Requirements: 2to3/host openwrt/packages#17429

Add upstream patch: 196c55e931

To install/build for python3 from source, it is necessary to convert to py3
codebase before setup (invoke 2to3 or ./fail2ban-2to3 firstly).
> ./fail2ban-2to3
> python3 setup.py build
