Cargo deny duplicated logs

When running cargo deny, the logs aer duplicated in build log, e.g.
```
cargo deny
09:19:24  starting: /bin/sh -c "/home/builduser/.cargo/bin/rustup run 1.88.0 cargo deny --manifest-path filewatcher_jni/Cargo.toml check 2>&1" rustup
09:19:24  in directory: /mnt/agent/work/cbcb6ed81773a54a
09:19:30  warning[wildcard]: found 1 wildcard dependency for crate 'filewatcher_jni'
09:19:30  warning[wildcard]: found 1 wildcard dependency for crate 'filewatcher_jni'
09:19:30  ┌─ /mnt/agent/work/cbcb6ed81773a54a/filewatcher_jni/Cargo.toml:12:9
09:19:30  ┌─ /mnt/agent/work/cbcb6ed81773a54a/filewatcher_jni/Cargo.toml:12:9
09:19:30  │
09:19:30  │
09:19:30  12 │ watch = { path = "../crates/watch" }
09:19:30  12 │ watch = { path = "../crates/watch" }
```

Reproduce the duplicated output with the cargo deny command shown in the issue, then trace how the TeamCity Rust plugin captures and renders that command's logs. Done means each warning and source-line entry appears only once in the build log.
