Artur Korzeniewski 4ed7de8f71 Neutron: fix reg exp for finding default tunneling interface
Grep the output from 'ip route' command matching first word after match.
The OVS was fixed some time ago, but in new linuxbridge the default
tunnel interface was following wrong grep expression.
Making both OVS and linuxbridge to follow the same reg exp.
