Xuan-Son Nguyen ee67d7f5f2 fix: sdfat warning about redefinition of macro (#1135)
## Summary

Fix redefinition of `FILE_*` macro.

Note that there will still be 2 warning:

```
.pio/libdeps/default/WebSockets/src/WebSocketsClient.cpp: In member function 'void WebSocketsClient::clientDisconnect(WSclient_t*, const char*)':
.pio/libdeps/default/WebSockets/src/WebSocketsClient.cpp:573:31: warning: 'virtual void NetworkClient::flush()' is deprecated: Use clear() instead. [-Wdeprecated-declarations]
  573 |             client->tcp->flush();
      |             ~~~~~~~~~~~~~~~~~~^~
```

--> I assume the upstream library need to fix it

And:

```
src/activities/Activity.cpp:8:1: warning: 'noreturn' function does return
    8 | }
      | ^
```

Will be fixed in #1016
