Having FOO include FOO.local is fine, but we still need a local include
file that is included by substantially every kernel.

The point is that if I decide that on my systems, I want some device
that isn't on by default, or to tweak something, and I want it on
everything, it should be easy.

In particular, I think it's normal to flip back and forth between
GENERIC and XEN3_DOM0 on the same machine, and those feel like they are
doing the same thing, modulo expecting a hypervisor.

Arguably, XEN3_DOM0 should just include GENERIC and then have any dom0
stuff added and some no stuff.

This feels like "we shouldn't have XEN kernels include what they have
included for years, because we found a latent config bug".
