tests: Update ovn localnet test case.
The OVN localnet port test case did not cover having 2 ports on the same
network and on the same hypervisor. It also turns out that this case is
broken. Update the test case to demonstrate the problem. A solution
should be able to uncomment these additional test_packet lines and have
the test case still pass.
