feat(controller): offer IOU the kernel datapath

Browse Source 
Eligibility gains an IOU branch gated on the compute's ubridge_iol_tap
(strict True: an unreported capability keeps the link on the relay), and
a port-level rule: a kernel link is an Ethernet segment, so any endpoint
whose port is not Ethernet (IOU serial) disqualifies the link before it
is dispatched. Without that, a serial link between two capable IOU nodes
would be sent as nio_bridge and fail at the compute.

The IOU NIO routes accept nio_bridge alongside the UDP/TAP/Ethernet NIOs
— without the widening the controller's POST is 422'd before the node
ever sees it, the same trap the QEMU routes hit.
