src: Add integration test for vhost-user-net backend

Browse Source 
An integration test relying on the new vhost-user-net backend now
replaces the previous test using the QEMU test backend. This allows
us to avoid building the QEMU backend, and we now really exercise the
vhost-user-net implementation as it is used for the ssh communication
in this test.
