python3-installer: bootstrap by installing installer with installer

The installer can install itself by simply adding src/ to PYTHONPATH.

As this previously used unzip, we need to disable bytecode as otherwise
the newly packaged .pyc files conflict with the any generated .pyc files
in the sysroot.
