    wireguard-tools: ipc: freebsd: use AF_LOCAL for the control socket
    
    AF_INET assumes that IPv4 is built into the kernel, but it's completely
    valid to build a kernel without it.  unix(4) sockets, on the other hand,
    are not-optional in the kernel build.  Given that interface ioctls can
    be invoked on any kind of socket, switch to the safer one to avoid
    breaking on IPv6-only kernels.
