[autotest] Force FQDN when trying to DNS-resolve www.google.com in CrosUITest setup

In the setup phase of CrosUITest, we fake out DNS by re-routing all
DNS resolution requests to a local DNS server.  We check that this has
been done by attempting a DNS resolution of 'www.google.com' and
expecting to get back  By forcing the use of a
fully-qualified-domain-name, we make the resolution attempt go
directly to the DNS server, bypassing any local potential sources of
failure or hanging.
