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.
