fails to build on openbsd

[brahin2]

using the Cargo.toml and example code from the README on openbsd i get the following:

% cargo run
   Compiling sysctl v0.5.4
error[E0433]: failed to resolve: maybe a missing crate `sys`?
  --> /home/MYUSER/.cargo/registry/src/index.crates.io-6f17d22bba15001f/sysctl-0.5.4/src/lib.rs:77:9

   |         ^^^ maybe a missing crate `sys`?
   |
   = help: consider adding `extern crate sys` to use the `sys` crate

Some errors have detailed explanations: E0432, E0433.
For more information about an error, try `rustc --explain E0432`.
error: could not compile `sysctl` (lib) due to 3 previous errors

adding target_os = "openbsd" to the lib where freebsd is ends up in a whole other errors and fails too.

Thanks for the report.

As it says in the README

FreeBSD, Linux, macOS and iOS are supported. Contributions for improvements and other platforms are welcome.

It's unlikely to work on any other OS out of the box. PRs for OpenBSD support are welcome.

just ran into this issue too.
maybe @semarie has thoughts.
