Fix compatibility with pytest 7.2

With pytest 7.2, the remaining parts of the "py.path" library got vendored, to
get rid of the dependency: pytest-dev/pytest#10396

However, this breaks due to pytest_mypy_plugins importing private API:

    File ".../pytest_mypy_plugins/collect.py", line 13, in <module>
        from py._path.local import LocalPath
    ModuleNotFoundError: No module named 'py._path'; 'py' is not a package

Use py.path.local instead (the public name of the same type), which is part of
the shim included in pytest.
