tests: fix test-clonebundles on recent openbsd I guess openbsd feels like it needs to stringify this errno in lowercase and omit the "host" part of "hostname. Okay. Reported in a big test diff talking about libressl, see 6122. I'm not flagging this because most of that issue is about a libressl string change, so this doesn't really make a big difference there.

rust-python3: compatibility fix for integer conversion On python3, `to_py_object()` on the usize gives us a PyLong, whereas it is the generic `PyObject` already on python2, which fits the `py.None()` default value.
