ct: add support for directional keys
A few keys in the ct expression are directional, i.e. we need to tell kernel if it should fetch REPLY or ORIGINAL direction. Split ct_keys into ct_keys & ct_keys_dir, the latter are those keys that the kernel rejects unless also given a direction. During postprocessing we also need to invoke ct_expr_update_type, problem is that e.g. ct saddr can be any family (ip, ipv6) so we need to update the expected data type based on the network base.
