setools: bump to 4.6.0

setools: bump to 4.6.0

Fix dependency with python3-pkg-resources (it got removed).
And add test.sh

- Bump from 4.5.1 to 4.6.0
- Drop python3-pkg-resources dependency: setools uses
  'from importlib import resources as pkg_resources' which is stdlib,
  not the external pkg_resources package
- Update 010-no-gui.patch: pyproject.toml now manages script-files and
  package-data (was setup.py in 4.5.1); rewrite patch to target it
- Update 030-remove-host-paths.patch: lib_dirs now uses list[str] type
  hint; fix hunk header line numbers to match new upstream layout
- Add test.sh: verify core query classes (SELinuxPolicy, BoolQuery,
  TypeQuery, RoleQuery, UserQuery) are accessible
