Re: [PATCH net-next] selftests: net: add ruff linter exclusions

Fedora is now shipping ruff 0.16 which added a ton of more
opinionated rules. Let's add some exclusions for checks
which are both noisy and IMO of questionable value.
We can still follow them for new code but it's a matter
of preference.

C401: set(x for x in Y) -> {x for x in Y}

I find the set() a little more readable.

I001: hard requirements to sort includes

A little too much

RUF015: list(set_a - set_b)[0] -> next(iter(set_a - set_b))

list + index are more readable to a "C person" for sure.
