python3-setuptools: upgrade 67.4.0 -> 67.6.0

Changelog:
=========
#3804: Added caching for supported wheel tags.
#3846: Added pruning heuristics to PackageFinder based on exclude.
#3843: Although pkg_resources has been discouraged for use, some projects still
consider pkg_resources viable for usage. This change makes it clear that
pkg_resources should not be used, emitting a DeprecationWarning when imported.
