py-setuptools: updated to 60.5.0

v60.5.0

Changes

* Set the .origin attribute of the distutils module to the module's __file__.

v60.4.0

Changes

* Removed requires sorting when installing wheels as an egg dir.
* Fixed a bug that easy install incorrectly parsed Python 3.10 version string.
* Fixed startup performance issue of Python interpreter due to imports of costly modules in _distutils_hack -- by :user:`tiran`
Documentation changes

* Added link to additional resources on packaging in Quickstart guide
* "In-tree" Sphinx extension for "favicons" replaced with sphinx-favicon.
* SVG images (logo, banners, ...) optimised with the help of the scour package.

Misc

* Added integration tests that focus on building and installing some packages in the Python ecosystem via pip -- by :user:`abravalheri`

* Modified "vendoring" logic to keep license files.

* Improved isolation for some tests that where inadvertently using the project root for builds, and therefore creating directories (e.g. build, dist, *.egg-info) that could interfere with the outcome of other tests -- by :user:`abravalheri`.

* Introduced new test fixtures venv, venv_without_setuptools, bare_venv that rely on the jaraco.envs package. These new test fixtures were also used to remove the (currently problematic) dependency on the pytest_virtualenv plugin.

* Removed tmp_src test fixture. Previously this fixture was copying all the files and folders under the project root, including the .git directory, which is error prone and increases testing time.

Since tmp_src was used to populate virtual environments (installing the version of setuptools under test via the source tree), it was replaced by the new setuptools_sdist and setuptools_wheel fixtures (that are build only once per session testing and can be shared between all the workers for read-only usage).
