Update path.py to 11.4.1

[pyup-bot]

This PR updates path.py from 11.3.0 to 11.4.1.

Changelog

11.4.1

------

- 153: Skip intermittently failing performance test on
Python 2.

11.4.0

------

- 130: Path.py now supports non-decodable filenames on
Linux and Python 2, leveraging the
`backports.os <https://pypi.org/project/backports.os>`_
package (as an optional dependency). Currently, only
``listdir`` is patched, but other ``os`` primitives may
be patched similarly in the ``patch_for_linux_python2``
function.

- 141: For merge_tree, instead of relying on the deprecated
distutils module, implement merge_tree explicitly. The
``update`` parameter is deprecated, instead superseded
by a ``copy_function`` parameter and an ``only_newer``
wrapper for any copy function.
