Don't reinstall python-virtualenv on infra nodes
In the original change I said "for infra nodes, it shouldn't do
anything anyway ...". Well that was pre-Fedora 26 :)
It seems that dnf > 2.0 now intentionally throws an error when trying
to explicitly install an ignored package. Thus, as described in the
comment, take a simpler approach of skipping this on infra nodes.
pip-and-virtualenv in dib should have installed the latest pip,
virtualenv and setuptools, so we don't want to fiddle with that
anyway.
