8b08d212c3
Now that DIB is python3 only we can remove a hack that made sure
scripts outside the chroot ran with the correct version of python.
This is necessary as python3 does not resolve symbolic links to the
binary like python2.x did, which causes element scripts to fail finding
modules when DIB was run from inside a venv.
This patch does the following:
1. Reverts 9c7b8d1714 which was the
workaround for mixed python2/3 environments.
2. Updates the scripts to use "python3" instead of "python".
