libnftnl: Fix res_id byte order

The res_id member of struct nfgenmsg is supposed to be in network
byte order (big endian).  Call htons() in __nftnl_nlmsg_build_hdr()
to ensure that this is true on little endian systems.

There is a kernel workaround that was introduced in 4.3 to address
this issue:

    netfilter: nfnetlink: work around wrong endianess in res_id field

And current oldest stable kernel branch in 4.9, merge this to fix
the incorrect endianness from userspace.
