    fix tox python3 overrides

    We want to default to running all tox environments under python 3, so
    set the basepython value in each environment.

    We do not want to specify a minor version number, because we do not
    want to have to update the file every time we upgrade python.

    We do not want to set the override once in testenv, because that
    breaks the more specific versions used in default environments like
    py35 and py36.
