mitmproxy: fix for python 3.11
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **briefly**

Without this patch, mitmproxy doesn't even start. I also disabled two tests that are broken with python 3.11.

Upgrading to 9.0.1 needs https://github.com/decathorpe/mitmproxy_wireguard which is a python module written in rust.
