[PATCH] fixup! fsmonitor-fs-listen-macos: implement FSEvent listener on MacOS

clang defines __GNUC__ for compatibility with gcc (indeed it misrepresents
itself as gcc 4.2.1), so instead use the __clang__ specific macro to
distinguish between them.

tested with Apple clang 12.0.5, clang 14 and gcc 11.2.0
