Continue the work to convert protocols to the new getsockopt_iter API. Convert AF_NETLINK and AF_VSOCK getsockopt implementations to the new sockopt_t/getsockopt_iter API, and add kselftests that verify the size and errno semantics are preserved across the conversion.
I chose these two socket families because they are probably one of the most used protocols,, ensuring that any potential bugs will be discovered and reported quickly. The selftest was added as suggested by Stanislav Fomichev in [1].
