QBONE Bonnet: Prepare for ability to split Read/Write fds in `TunDevice`.

This modifies the `TunDeviceInterface` API such that it has separate accessors for a read and a write file descriptor. For now, the concrete implementation is unmodified and returns its single file descriptor from both, matching current behavior.

A future implementation of the interface could in theory open and return distinct fds.
