Empty iterator on OpenBSD.

Hi,

This is kind of expected (as you clearly say you only support Linux and Mac right now), but findshlibs doesn't work on OpenBSD:

extern crate findshlibs;
use findshlibs::{Segment, SharedLibrary, TargetSharedLibrary};

fn main() {
    println!("hello");
    TargetSharedLibrary::each(|shlib| {
        println!("{}", shlib.name().to_string_lossy());

        for seg in shlib.segments() {
            println!("    {}: segment {}",
                     seg.actual_virtual_memory_address(shlib),
                     seg.name());
        }
    });
    println!("/hello");
}

prints:

hello
/hello

It probably isn't difficult to get this working on OpenBSD. Before I heard of findshlibs I wrote a similar lib called phdrs which does work on OpenBSD. IIRC the callback struct is a little different, but the API is pretty much the same.

If you want to get *bsd support working in findshlibs, that would be most welcome!
