wgctrl-go internal/wgopenbsd: add configuration for OpenBSD kernel devices

An OpenBSD kernel implementation is being built, and the source can be found at https://git.noconroy.net/wireguard-bsd.git.

The userspace interface types can be found here: https://git.noconroy.net/wireguard-bsd.git/tree/src/if_wg.h.

We should support this interface in wireguardctrl.

A branch of wg which supports this interface: https://git.noconroy.net/WireGuard.git/tree/src/tools/ipc.c?h=ncon/openbsd.

The read-only portion of this code is done. Configuring OpenBSD devices will take more work.

I've implemented the updated read-only interface and plan to do the configuration API soon!

@mdlayher I am planning to pick up this work. Are there any major obstacles? Or do you still have a branch with some WIP code?

@stv0g please do, thanks! I implemented this as an experiment and chance to learn, but never got to the configuration.
