```
zig.h: do not assume __GNUC__ is not clang

A followup to 5bd69c655d9e04102c8a64ced1215c9d69f4f03f .

For compatibility purposes clang defines __GNUC__. This broke logic
where clang14 __has_builtin returns false but `|| defined(__GNUC__)`
made it true.

CI did not catch this because it uses clang15. However, bootstrapping
with latest apple compiler is clang14. We also want to support older
clang.
