Define NO_KDS in ttyclicks.c.

It really shouldn't be here, really it should be managed by make,
but I've virtually given up on getting any of my stuff into the kernel, ever,
so I'll just assume my kd sounds will never make it in,
and disable them right here in the source.
tty interface changes between 3.2 and 3.12.
Use the insert flip string function, but pass tty or port depending on version.
