ci(kitchen+travis): use latest pre-salted images

* Automated using myii/ssf-formula#207
* Use `bionic` for Travis (also no longer need to use `pip3`)
* Add `without-ipv6` suite, to avoid errors with `ip6tables` such as:

```
[ERROR   ] stdout: ERROR: initcaps
[Errno 2] ip6tables v1.8.4 (legacy): can't initialize ip6tables table `filter': Table does not exist (do you need to insmod?)
Perhaps ip6tables or your kernel needs to be upgraded.
```
