Subject: [PATCH] fix(sgx-ra): Fix building when enclave is built without
 librats ahead (#2968)

This PR addresses the issue with building the sgx-ra sample when the enclave under
the path product-mini/platforms/linux-sgx/enclave-sample is built beforehand.

When the enclave is built without librats ahead, an error occurs as the following
without the changes:
```bash
...
CP libvmlib.a  <=  /home/haoxuan/wasm-micro-runtime/samples/sgx-ra/build/libvmlib.a
/usr/local/bin/ld: libvmlib.a(lib_rats_wrapper.c.o): in function `librats_collect_wrapper':
lib_rats_wrapper.c:(.text.librats_collect_wrapper+0x4a): undefined reference to `wasm_runtime_get_module_hash'
collect2: error: ld returned 1 exit status
```
