[pyup-bot]

This PR updates wheel from 0.37.1 to 0.38.0.

Changelog

0.38.0

- Dropped support for Python < 3.7
- Updated vendored ``packaging`` to 21.3
- Replaced all uses of ``distutils`` with ``setuptools``
- The handling of ``license_files`` (including glob patterns and default
values) is now delegated to ``setuptools>=57.0.0`` (466).
The package dependencies were updated to reflect this change.
- Fixed potential DoS attack via the ``WHEEL_INFO_RE`` regular expression
- Fixed ``ValueError: ZIP does not support timestamps before 1980`` when using
``SOURCE_DATE_EPOCH=0`` or when on-disk timestamps are earlier than 1980-01-01. Such
timestamps are now changed to the minimum value before packaging.
