fix: patching pypy venv (#502)

Potentially revert / remove on release of PyPy 7.3.4.

* patching linux and macos

* try test

* add patch files for pypy2.7

* fix installing

* Combine patch files into one

* Simplify further, and add test to remind ourselves to remove the PyPy patch

* ignore fail of patch on linux

make new test failing only on linux

* fix test

* add timeout

* fix patch on linux

* change `-N` to `--force`
