[dev.fuzz] cmd/go: skip fuzz tests on unsupported platforms

For now, fuzzing is only supported on Darwin, Linux, and Windows. We
haven't testing shared memory communication between coordinator and
worker processes on other platforms. Currently, fuzz.CoordinateFuzzing
and RunFuzzWorker both panic with "unimplemented" messages.

Unfortunately, these may be masked by runtime.Goexit calls that
override panics, so some builders fail with

    test executed panic(nil) or runtime.Goexit
