netlink: specs: fou: local-v4 and peer-v4 are big endian

Browse source

fou_core.c uses nla_get_in_addr() / nla_put_in_addr() on both, i.e.
they are __be32, and port / peer-port in the same spec are already
annotated. Without byte-order YNL swaps them on little endian hosts.

The generated policy goes from NLA_U32 to NLA_BE32, which changes
nothing: lib/nlattr.c gives the two the same length in nla_attr_len[]
and the same range handling, and neither attribute has a range check.
