shill: Connection: Create a link route if we are bound

Due to the behavior of some VPN servers, we may lose our route
to the default gateway of a physical interface due to the routes
assigned by a virtual interfaces.  To avert this, set a host route
for the default gateway as we bind a lower connection.

BUG=chromium-os:32643
TEST=New unit tests; tried on a known-misbehaving net (actually
working from there right now); VPN autotests
