sysctl: clean headers, ensure SYS__sysctl is def'd
Linux/aarch64 does not define SYS__sysctl. This caused build errors in Alpine[1] and Void[2]. While I'm in here, fix up headers since we don't need errno or strings. [1]: https://git.alpinelinux.org/cgit/aports/commit/?id=400a9d40 [2]: https://github.com/voidlinux/void-packages/commit/a7aa924e
