Fix test failure when no IPv6 is avail

When the system doesn't have IPv6 available (e.g. not built into the
kernel or the module isn't loaded), you can not create an IPv6 socket.
The test determines earlier on that IPv6 isn't available then goes and
creates a socket. This makes socket creation conditional on IPv6
availability.
