selftests: drv-net: rss_ctx: Add test for ntuple rule 



Extend the rss_ctx test suite to test that an ntuple action that
redirects to an RSS context contains that information in `ethtool -n`.
Otherwise the output from ethtool is highly deceiving. This test helps
ensure drivers are compliant with the API.
