Doing a better guess for Opossum when tcp/80 is not a/v

This labels the result of a failed test for reaching
port 80 when no direct connection is possible as likely not
vulnerable.

This seems safe to say, as there's another check whether
a proxy is configured, like for corporate environments where
a connection is only allowed though the proxy.
