[PATCH 5/7] tests/docker: use direct RUNC call to build containers

["Alex Bennée" <alex.bennee@linaro.org>]

We don't really need stuff from docker.py to do the build as we have
everything we need with a direct call. We do rely on the dockerfiles
being able to tweak the UID/name mapping as the last step.
