[wasm][fuzzer] Stack overflow is nondeterministic

Before the introduction of exception handling in the compile fuzzer,
stack overflows were deterministic because they always caused the whole
stack to be unwound.
With support for exception handling, the stack overflow exception can be
caught and is a source of nondeterminism. Flag the interpreter result as
such in this case so that we skip the correctness check.
