Update fuzzer for new WasmNode::Create signature (#351)
Update fuzzer for new WasmNode::Create signature (#351)

Commit edb3a73a8930 ("Add owning-runtime link to Wasm node") changed
the signature of WasmNode::Create, but the fuzzer driver wasn't updated
at the time (and wasn't noticed because CI doesn't build this target).
