update NetworkPolicy e2e test for v1 semantics
This makes the NetworkPolicy test at least correct for v1, although ideally we'll eventually add a few more tests... (So this covers about half of #46625.)
I've tested that this compiles, but not that it passes, since I don't have a v1-compatible NetworkPolicy implementation yet...
@caseydavenport @ozdanborne, maybe you're closer to having a testable plugin than I am?
**Release note**:
