- Detect active network interface to use, instead of asking user, this needs
to run in automation
- Find the location of ppp_null.so with find instead of rpm, rpm is a distro choice

- Add missing runtime deps for ptests
- Kill openl2tpd started by run-ptest script before exiting, otherwise
ptest runner hangs forever.
