netlink: specs: rt-neigh: prefix struct nfmsg members with ndm

Attach ndm- to all members of struct nfmsg. We could possibly
use name-prefix just for C, but I don't think we have any precedent
for using name-prefix on structs, and other rtnetlink sub-specs
give full names for fixed header struct members.
