chore(tracing): Refactor tracing_utils.py

[rominf]

Preparation for:
#3313
Proposed in:
#3313 (comment)

Note that the _module_in_list function returns False if name is None or items are falsy, hence extra check before function call can be omitted to simplify code.

Thank you for contributing to sentry-python! Please add tests to validate your changes, and lint your code using tox -e linters.

Running the test suite on your PR might require maintainer approval. The AWS Lambda tests additionally require a maintainer to add a special label, and they will fail until this label is added.

Thanks for the contribution! Code looks much cleaner this way.

I also made a further simplification to the should_be_included logic
