LOG: [libc] Correct hidden attribute on __restore_rt (#220039)

This PR fixes the syntax for a `hidden` attribute in `__restore_rt`.
When compiling with `-Wattributes`, this TU complains about:

```
llvm-project/libc/src/signal/linux/__restore.cpp:20:67: error: unknown attribute 'hidden' ignored [-Werror,-Wunknown-attributes]
   20 | extern "C" void __restore_rt() __attribute__((no_sanitize("all"), hidden));
```

Added: 
    

Modified: 
    libc/src/signal/linux/__restore.cpp

Removed:
