Merge #18008: test: only declare a main() when fuzzing with AFL
b35567fe0ba3e6f8d8f9525088eb8ee62065ad01 test: only declare a main() when fuzzing with AFL (fanquake)
Pull request description:
This fixes fuzzing using [libFuzzer](https://llvm.org/docs/LibFuzzer.html) on macOS, which caused a few issues during the recent review club. macOS users could only fuzz using afl, or inside a VM.
It seems that the `__attribute__((weak))` marking is not quite enough to properly mark `main()` as weak on macOS. See Apples docs on [Frameworks and Weak Linking](https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html#//apple_ref/doc/uid/20002378-107262-CJBJAEID).
Have tested fuzzing using libFuzzer and AFL with this patch.
