Drop bpf_iter.h header which uses vmlinux.h but re-defines a bunch of iterator structures and some of BPF constants for use in BPF iterator selftests. None of that is necessary when fresh vmlinux.h header is generated for vmlinux image that matches latest selftests. So drop ugly hacks and have a nice plain vmlinux.h usage everywhere. We could do the same with all the kfunc __ksym redefinitions, but that has dependency on very fresh pahole, so I'm not addressing that here.
