netmon: Fix bug in how routes are converted

Browse Source 
The agent expects a IP CIDR for the route destination
rather than an IP address. netmon was incorrectly
converting route dest to an IP address and hence
exiting with an error.

We did not have an integration test for netmon with tcfilter mode.
macvtap mode did not uncover this, as with macvtap routes are
not really passed to the agent.
We delete the IP on the veth device, and netmon looks at the
routes after the IP is deleted with macvtap.

Fixes #1523
