Fix setup.sh jpegio build order and add python3-dev

- Clone stegasoo BEFORE building jpegio (need patch script)
- Create venv with explicit pyenv Python path
- Build jpegio INTO venv (not globally)
- Add python3-dev to apt dependencies
- Update step count from 9 to 11

This fixes the issue where jpegio was built globally, then pip
tried to reinstall unpatched jpegio from PyPI into the venv.
