Use ensure-pip for stackviz pip install

Infra is trying to move to nodes that do not come with pip/virtualenv
pre-installed on the image; for details see the spec at [1].

zuul-jobs include ensure-pip [2] to provide pip dependencies; use that
before installing stackviz.  Note that if pip is installed this is a
noop.
