CI: install Pipfile into system interpreter

A virtual environment is redundant in the context of deployment. It
just increases the size and build time of the image.

* Replace venv with system interpreter
* Mount Python binaries in /usr/local/bin in NsJail
* Fix #61: Python symlink in venv not resolving
* Re-lock Pipfile because it wasn't up to date according to
  pipenv install --deploy
