selftests/bpf: Convert bpf_iter_test_kern{3, 4}.c to define own bpf_iter_meta

b9f4c01f ("selftest/bpf: Make bpf_iter selftest compilable against old vmlinux.h")
missed the fact that bpf_iter_test_kern{3,4}.c are not just including
bpf_iter_test_kern_common.h and need similar bpf_iter_meta re-definition
explicitly.
