 set az_installer to deb
 The AZ_INSTALLER variable influences the az upgrade command behaviour.
 For the packaged version, we want it to simply run apt update/upgrade, so
 always set it to DEB.

 {az} use runpy instead of os.execl
 python -m adds the current working directory to the start of sys.path,
 which means running from say /tmp with a fake azure.py causes az to load
 it and run it.
