Kui-Feng Lee c911fc61a7 libbpf: Skip zeroed or null fields if not found in the kernel type. ...

Accept additional fields of a struct_ops type with all zero values even if
these fields are not in the corresponding type in the kernel. This provides
a way to be backward compatible. User space programs can use the same map
on a machine running an old kernel by clearing fields that do not exist in
the kernel.
