This, beyond causing linux image problems we haven't investigated too deeply, also increases our image almost three-fold. See [0] for github discussion on topic. So for now I'm going to disable sk_assign selftest permanently in libbpf tests. Ideally sk_assign can be written to not rely on iproute2 to set things up. But until then, it won't be exercised in libbpf's CI tests, unfortunately.
