tests: Have `getaddrinfo' test work for Darwin 8.

Browse source 
* doc/ref/posix.texi (Network Databases): Update description of
  `EAI_NODATA' to mention that Darwin provides it.

* libguile/net_db.c (scm_getaddrinfo): Likewise.

* test-suite/tests/net-db.test ("getaddrinfo")["wrong service name"]:
  Accept `EAI_NODATA' too.  Reported by David Fang <fang@csl.cornell.edu>,
  see <http://bugs.gnu.org/10684>.
