After some consideration, I decided to remove the cfg_if entirely and rely on libc to have the correct struct definition instead. If something turns out to be incorrect, it only needs to be fixed in one place :)

This can just always be a usize, because it's only ever passed to slice::from_raw_parts.

This PR is a small maintainability improvement. It simplifies
unix/net/ancillary.rsinstdby removing thecfg_ifsfor casting to the correct integer type, and just rely on libc to define the struct correctly.
