OpenBSD: EPROTO available since 6.2

[rennis250]

Hello,

I was recently trying to use the latest version of glium (v0.23) on OpenBSD, which depends on a newer version of wayland-client (v0.21), that depends on v0.12 of nix, but it unfortunately does not build. While I realize that v0.13 compiles and works correctly on OpenBSD, forcing glium to use a newer version of wayland-client that depends on nix v0.13 does not fix the issue because wayland-client makes use of EPROTO, which is not provided by the nix crate on OpenBSD. EPROTO was added around OpenBSD 6.2 (https://man.openbsd.org/OpenBSD-6.2/errno), so it is safe to make it available via this crate on OpenBSD also.

Many thanks,
Rob

Ah, I see this is already in discussion: #1036

Closed due to #1036 being merged.
