Andrii Nakryiko e626a13f6f selftests/bpf: drop unnecessary bpf_iter.h type duplication
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.

Yonghong Song 9efcc4ad7a selftests/bpf: Add a test for out of bound rdonly buf access
If the bpf program contains out of bound access w.r.t. a
particular map key/value size, the verification will be
still okay, e.g., it will be accepted by verifier. But
it will be rejected during link_create time. A test
is added here to ensure link_create failure did happen
if out of bound access happened.
  $ ./test_progs -n 4

  #4/23 rdonly-buf-out-of-bound:OK
