The PYTHONPATH env var (and all other env vars) are set at the OS level
which means they are fixed at the time the jenkins slave starts.

We periodically upgrade RPMs via dnf, and this time python got
upgraded to 3.8.  The slave's PYTHONPATH still says 3.7 though.

I'll reboot the VM to fix it shortly.

Really we should be setting all build related env vars in the job
script, so that they are guaranteed accurate when each job runs.

Regards,
Daniel
