Setting PYTHON3=no for LOCI images

Recently, LOCI changed its default so images are python3 if nothing is
specified at the *docker_image files. With the recent upversion of LOCI
in the build tools [1], we need to explictly set PYTHON3=no to images
that are still using python2. This commit fixes the StarlingX images to
use this parameter.

This will also remove all PYTHON3=yes since it's the detault now to
reduce uneeded LOCs and ease maintenance.

TEST PLAN
PASS build the stx-nova on the stable branch
PASS build the stx-openstackclients on the stable branch
PASS build the stx-platformclients on the stable branch
