Its value has always been "", unless the deity recompiled with
RESOLVE_IPADDRESS defined, or imported another value with empdump.
I'm going to drop the RESOLVE_IPADDRESS code, including struct natstr
member nat_hostname. To prepare for that, fix the selector's value to
"", so it doesn't need nat_hostname, and deprecate it.
This changes its "len" in xdump meta nat from 512 to 0. Unlikely to
upset clients.
