test/e2e/network: add a check to the hostport e2e test
test/e2e/network: add a check to the hostport e2e test

As described in 8c76845b038 ("test/e2e/network: fix a bug in the hostport e2e
test") if we have two pods with the same hostPort, hostIP, but different
protocols, a CNI may be buggy and decide to forward all traffic only to one of
these pods. Add a check that we receiving requests from different pods.
