[U-Boot] [PATCHv3 12/13] gitlab/travis: Rework how and when we use virtualenv in order to use python3

[Tom Rini <trini@konsulko.com>]

As things stand today, we have tools that CI requires where "python"
must be "python2".  We need to use a virtualenv and pip in order to
ensure that our pytest tests can be run.  Rework things slightly so
that:
- On Travis-CI, we install python-pyelftools for the platforms that
  require pyelftools to be installed.
- On GitLab-CI, we move to a newer base image that includes python3-pip
  and continue to use a virtualenv per job that needs it, for the
  correct set of packages.

Changes in v2:
- Add Travis-CI support here, and stop calling it a work-around.  This
  is just the path forward until we have everything using python3 and at
  that point evaluate what the right changes, if any, are.
