Ian Wienand 6d78fc4f90 ensure-tox: use venv to install
This currently installs with pip --user which cases problems if you
try to run this version of tox as another user.  This is done in
system-config, for example, where we run tox with "become: yes" to run
testinfra.

By installing tox into a venv, we can call it as another user and it
just works because it's all encapsulated in the venv.  We use the
virtualenv commands exported by ensure-pip to create this.

I think the original motivation for installing tox like this was to
ensure it is done without sudo permissions.  This also doesn't require
permissions, but ensures the resulting tox_executable is able to be
executed in more contexts.
