chore: fix type checking issues

[mayeut]

pyelftools recently released a version with typing hints.
auditwheel fails to pass mypy checks with this new version.

This PR aims to fix (or ignore) mypy reported issues.

[mayeut]

This could be made a runtime check but this way, we ensure the exact same runtime behaviour as before.

All the # type: ignore[attr-defined] are for dynamically defined attributes

Pull request overview

This PR updates auditwheel’s code and integration tests to satisfy mypy when used with newer pyelftools versions that ship richer type hints.

Changes:

• Add explicit DynamicSection / segment type narrowing (isinstance(...)) where .dynamic sections and PT_* segments are accessed.
• Add targeted # type: ignore[attr-defined] annotations for pyelftools tag attributes not represented in stubs.
• Update the pre-commit mypy hook environment to use pyelftools>=0.33.
