logging(fix): Use the proper log target for logging (#4124)

This PR ensures the proper logging target (ie `libp2p_tcp` or `beefy`)
is displayed.

The issue has been introduced in:
https://github.com/paritytech/polkadot-sdk/pull/4059, which removes the
normalized metadata of logs.

From
[documentation](https://docs.rs/tracing-log/latest/tracing_log/trait.NormalizeEvent.html#tymethod.normalized_metadata):

> In tracing-log, an Event produced by a log (through
[AsTrace](https://docs.rs/tracing-log/latest/tracing_log/trait.AsTrace.html))
has an hard coded “log” target

>
[normalized_metadata](https://docs.rs/tracing-log/latest/tracing_log/trait.NormalizeEvent.html#tymethod.normalized_metadata):
If this Event comes from a log, this method provides a new normalized
Metadata which has all available attributes from the original log,
including file, line, module_path and target

This has low implications if a version was deployed containing the
mentioned pull request, as we'll lose the ability to distinguish between
log targets.
