libdns: Avoid using compound literals (7).

Browse source 
* dirmngr/dns.h (DNS_OPTS_INIT, dns_opts): Remove.
* dirmngr/dns-stuff.c (libdns_res_open): Use zero-ed, and initialized
automatic variable for opts.
* dirmngr/dns.c (send_query, resolve_query, resolve_addrinfo):
Likewise.

In fact, DNS_OPTS_INIT was only needed when args are none.  With
partially specified initialization, C99 guarantees zero-ed other
members just like static object.
