facedetection包含的libmnnfacedetection.so存在编译选项相关安全风险，请关注解决

facedetection-0.0.5.aar中的resources\jni\arm64-v8a\libmnnfacedetection.so，没有使用-fstack-protector-all或-fstack-protector-strong编译选项。可能导致缓冲区溢出攻击漏洞，导致应用程序被恶意劫持或崩溃。
按编译器不同：
1.GCC4.9版本及以上可使用-fstack-protector-strong进行加固
2.GCC4.9版本以下可使用-fstack-protector-all进行加固

请facedetection提供经过安全的编译选项加固后的so，谢谢

Start with facedetection-0.0.5.aar and inspect resources/jni/arm64-v8a/libmnnfacedetection.so, then locate the build configuration that produces this native library. Verify the rebuilt .so uses the requested stack-protection compiler option and confirm the secured library is included in the AAR.
