python3-wheel: upgrade 0.38.0 -> 0.38.4

Changelog:
===========
-Fixed PKG-INFO conversion in bdist_wheel mangling UTF-8 header values in METADATA
-Fixed install failure when used with --no-binary, reported on Ubuntu 20.04,
 by removing setup_requires from setup.cfg
-Fixed regression introduced in v0.38.1 which broke parsing of wheel file names
 with multiple platform tags
-Removed install dependency on setuptools
-The future-proof fix in 0.36.0 for converting PyPy's SOABI into a abi tag was
 faulty. Fixed so that future changes in the SOABI will not change the tag.
