Also, install pip packages in local
out/python_deps
directory insteadof installing system wide.
This means we can consistently expect dev dependencies to be available
in test code without needing to include an opt out mechanism.
We were already doing this for
psutil
, but forwebsockify
we madeit optional.
This means that only python scripts that explicitly add
out/python_deps
to their python path will be able usethe packages, and in particular it means that the emscripten compiler
itself won't end up implicitly/accidentally depending on them.
