21889437 - Avoid removing existing directories when unzipping and building (#577)

Avoid removing existing directories when unzipping and building (#577) Now that we don't store zipped and unzipped wheels at the same location, we can avoid these safeguards that entail removing existing directories when writing. This supersedes https://github.com/astral-sh/puffin/pull/545. Closes https://github.com/astral-sh/puffin/issues/554.
