[PATCH 2/3] silence warning about running pip as root in docker build

silence the warning about running pip as root when building docker image.  use
environment variable instead of command line flag because the version of pip
running initially is older than the flag, so including the flag causes it to
fail.  the environment variable just gets ignored by the older version of pip.
