Call into libSystem (Darwin's libc equivalent) to do system calls. Raw syscalls are not a supported ABI on Darwin, they want us to use libSystem calls instead. The stdlib has already been converted to this new regime. This package is vendored into the stdlib, so we need to fix it also, then vendor it in again. Because this package isn't tied to a Go release, we need to keep the old code around and use the new code only for 1.12 and up.
