Add more BSDs to the official builds

[juanfra684]

Hi, can you add more BSDs to the official builds?. Something like: openbsd/amd64, openbsd/386, netbsd/amd64, netbsd/386, dragonfly/amd64.

Thanks for the tool. I tested it on OpenBSD/amd64 and works like a charm.

Looks like wireguard-go doesn't compile currently for netbsd & dragonfly. I've added openbsd though.
