sunrpc: Always obtain AF_INET addresses from NSS [BZ #20964]
The new __libc_rpc_gethostbyname function calls gethostbyname2_r
with an AF_INET argument and is therefore not affected by the
RES_USE_INET6 flag.
Validated with the following test program, with and without
RES_OPTIONS=inet6, against a NFS server. (Link with -lrpcsvc.)
#include <rpc/clnt.h>
#include <rpcsvc/mount.h>
#include <stdio.h>
#include <string.h>

argv[0]);
