bump(sys-kernel/coreos-kernel): New modular kernel.

Lots of changes here, some things of note:
 - Switch from built-in to modules for much of the kernel.
 - Enable more features, mostly in power management and networking.
 - Remove no_firmware.patch, this was added back when we had two
   different kernels which would conflict if both installed firmware.
 - Stop disabling OUTOFTREE_BUILD now that we don't patch the source.

So far this is just compile tested so it is marked ~amd64 for now.
