When the NH group stats tests are currently run on a veth topology, the HW-stats leg of each test is SKIP'ped. But kernel networking CI interprets skips as a sign that tooling is missing, and prompts maintainer investigation. Lack of capability to pass a test should be expressed as XFAIL.
Selftests that require HW should normally be put in drivers/net/hw, but doing so for the NH counter selftests would just lead to a lot of duplicity.
So instead, introduce a helper, xfail_on_veth(), which can be used to mark selftests that should XFAIL instead of FAILing when run on a veth topology. On non-veth topology, they don't do anything.
Use the helper in the HW-stats part of router_mpath_nh_lib selftest.
