test: allow EAI_FAIL in test-net-dns-error.js

Test test-net-dns-error.js causes assertion failure on SunOS, test expects ENOTFOUND, but OS returns EAI_FAIL. Maximum length of a host name is 63 characters. Test test-net-dns-error.js makes a connection attempt to invalid host name (longer than maximum). Such connection attempt on SunOS returns permanent failure (EAI_FAIL) as invalid hostname won't be ever resolved.
