The problem was found by a `Golang + WAMR (as CGO)` wrapped by EGO in SGX Enclave. `fstat()` in EGO returns dummy values: - EGO uses a `mount` configuration to define the mount points that apply the host file system presented to the Encalve. - EGO has a different programming model: the entire application runs inside the enclave. Manual ECALLs/OCALLs by application code are neither required nor possible. Add platform ego and add macro control for the return value checking of `fd_determine_type_rights` in libc-wasi to resolve the issue.
