Currently, {autoninja, autoninja.bat} scripts generate AUTONINJA_BUILD_ID by calling `python3 -c "import uuid; print(uuid.uuid4())"`.
This CL moves the logic at the beginning `autoninja.py`.
This also reduces the overhead of starting Python interpreter, which
takes around 60ms on my Windows workstaion.
