ofproto-dpif.at: Add test for normal action with OFPP_NONE in_port.
Commit 33158a (ofproto-dpif: Fake-up OFPP_NONE input bundle for
mirroring and normal.) fixed handling of packets sent from a controller
with an ingress port of OFPP_NONE. It includes a unit test for the
mirroring case, but not the "normal" processing case. The reason is
that the test requires commit fadc05 (ofproto-dpif: Fix nondeterministic
flow revalidation behavior.), which removes a check that causes the test
to fail. That fix isn't available in all branches that 33158a is on, so
this test is only being run on those that are.
