Go binding: Change C.long to C.int64_t when call wasm_runtime_set_wasi_args_ex (#3235)

- Change `C.long` to `C.int64_t` due to error:
```sh
./module.go:119:64: cannot use _Ctype_long(stdinfd) (value of type _Ctype_long) as _Ctype_longlong value in variable declaration
./module.go:120:43: cannot use _Ctype_long(stdoutfd) (value of type _Ctype_long) as _Ctype_longlong value in variable declaration
./module.go:120:60: cannot use _Ctype_long(stderrfd) (value of type _Ctype_long) as _Ctype_longlong value in variable declaration
```
- Change offset from `uint32` to `uint64` due to casting error
