The 'bin/tests/system/resolver.c' tool used in the resolver system
test uses the 'dns_client_setservers()' function, which sets up a
resolution in 'forward only' mode. Since a bug was just fixed in
'fctx_getaddresses()', two expected failures in the resolver system
test now fail with a different failure message, because
'fctx_getaddresses()' returns 'ISC_R_FAILURE' instead of
'res->quotaresp[dns_quotatype_server]', which is 'DNS_R_SERVFAIL'
by default. Change the expected failure message.
