C API: Use `enum` instead of `#define` for better codegen

Is your feature request related to a problem? Please describe.
Currently Rust bindgen generates u32 for #define NIX_OK, but nix_err is an int. This then requires an undue cast.
Other code generators will also have trouble associating a type with these, but a C enum could solve the problem.
Describe the solution you'd like
enum nix_err
Describe alternatives you've considered
Maybe some code generators don't know how to deal with enum's. I would consider such a code generator to be very unfinished.
