nodepool: infra-package-needs; cleanup tox installs

The package-maps install of tox is only defined for gentoo, and that
came in with the original image build parts.  We don't need that any
more.

10-pip-packages I didn't trace down, but it hasn't been doing anything
for a long time, since we removed pip-and-virtualenv.  We can remove
that.

The install done in 40-install-tox I can not see being used anywhere.
It came in with If5397d731e9fb04431482529aed23cd9fdaecc1d but I can't
see the venv actually referenced anywhere.  I think this has all been
replaced by the ensure-tox role (or, indeed, jobs migrating away from
tox).  Remove it.
