586: Update dependencies r=Dirbaio a=alexandrasandulescu

Hi. This PR bumps smoltcp dependencies version to `latest` according to [crates.io](https://crates.io/).
The `env_logger` update brings an API change, the [parse](https://docs.rs/env_logger/0.5.0/src/env_logger/lib.rs.html#380-383) Builder method was replaced with [parse_filters](https://docs.rs/env_logger/0.9.0/env_logger/struct.Builder.html#method.parse_filters).

Apart from `parse_filters`, I noticed that the original code parsed `RUST_LOG` **after** setting the log level to `trace` and parsing the filters. My understanding is that this overwrites the builder setup with what `RUST_LOG` contains.
My change parses the [default environment](https://docs.rs/env_logger/0.9.0/env_logger/struct.Env.html#default-environment-variables) first with `from_default_env` and then applies the filter changes.

If the desired behaviour is the original one (overwrite `setup_logging_with_clock` filters with the ones defined by `RUST_LOG`) let me know.

Tnx :)
