consoles: Pass onSecurityFailure handler to VncConsole

It is not optional and VncConsole will crash otherwise when there is a
authentication failure.

Authentication failures should not happen since we pass the correct
credentials to VncConsole. However, manually setting a empty password
in the machine XML can trigger a authentication failure, and we should
be prepared for everything, of course.
