Executables with opencv-python>=4.5.4 fail

[JJReyka]

Describe the bug
After building an executable which depends on the latest (4.5.4) version of opencv-python, this error ocurrs on running:

ImportError: OpenCV loader: missing configuration file: ['config.py']. Check OpenCV installation.

When comparing the lib/cv2 folder produced by cx_Freeze to lib/site-packages/cv2 in a python environment, the files config.py and config-{python_version}.py (config-3.8.py in my case) are missing.

From this issue, it seems that recent updates to opencv-python have made it more difficult for tools to infer what files are required. Adding the following to hooks.py makes things work, but I don't know enough about cx_Freeze to say whether this does things in the right way, or even if it works beyond my machine.

def load_cv2(finder: ModuleFinder, module: Module) -> None:
    """The cv2 module requires additional configuration files"""
    dest_dir = Path("lib", "cv2")
    cv2_dir = module.path[0]
    for path in cv2_dir.glob("config*.py"):
        finder.IncludeFiles(path, dest_dir / path.name)

To Reproduce
This bug is present for any application build with opencv-python>=4.5.4 as a dependency.

Expected behavior
I expected things to work the same as when I was using version 4.5.3

Desktop (please complete the following information):

• Platform information (e.g. Ubuntu Linux 16.04): Windows 10
• OS architecture (e.g. amd64): amd64
• cx_Freeze version [e.g. 6.6]: 6.8.1
• Python version [e.g. 3.9]: 3.8

Can you make a PR?
And can you test the hook with opencv-python 4.5.3 to check if it doesn't break previous versions?
