tox.ini: only use sitepackages for "native" py3 envs

We need to use sitepackages for stuff that comes from the system like
samba libs and other compiled C stuff. This seems to be the only way
to get system packages when running the "native" py3 environments,
but skip them when checking stuff on our minimal supported python
version.
