[NETLINK]: Introduce nested and byteorder flag to netlink attribute
This change allows the generic attribute interface to be used within
the netfilter subsystem where this flag was initially introduced.
The byte-order flag is yet unused, it's intended use is to
allow automatic byte order convertions for all atomic types.
