Trac #30923: tox.ini: Add environments local-sudo-ubuntu-standard, etc.

These environments would just run `sudo apt-get ...` etc. to install
(but not remove!) packages, for use at the user's own risk.

To test (on an Ubuntu system):
{{{
    tox -e local-sudo-ubuntu-bionic-standard
}}}
or
{{{
    tox -e local-sudo-standard
}}}
