`AttributeError: module '_tkinter' has no attribute '__file__'` with indygreg standalone CPython distribution

## Description of the issue

When trying to run PyInstaller in a GitHub environment setup by https://github.com/astral-sh/uv, I get the following error:
https://github.com/Toufool/AutoSplit/actions/runs/13106302183/job/36561641009?pr=313#step:5:163

Looks like this issue was introduced in https://github.com/pyinstaller/pyinstaller/pull/8722/files#diff-63a9cf452f7a379d945e5f6ba92a579b783c471f3babe2d74ff2696610d727c4R60

Whilst searching for similar issues, I found that matplotlib had a similar issue with TK. Quoting from
https://github.com/matplotlib/matplotlib/issues/23074 :
> In the [python-build-standalone](https://github.com/indygreg/python-build-standalone) cpython distributions, `_tkinter` is doesn't have a separate shared library and therefore also doesn't have a `__file__` attribute, causing a crash

https://github.com/astral-sh/python-build-standalone/issues/129
> On system python, _tkinter is a shared library (`/usr/lib/python3.8/lib-dynload/_tkinter.cpython-38-x86_64-linux-gnu.so`), while in these python builds it's a builtin module which does not have `__file__`.

https://github.com/astral-sh/python-build-standalone/issues/129#issuecomment-1131857858
> My general response to this is: `__file__` is documented as optional by Python: any code requiring `__file__` is bugged and should instead be using a mechanism described in [pyoxidizer.readthedocs.io/en/pyoxidizer-0.20.0/oxidized_importer_resource_files.html](https://pyoxidizer.readthedocs.io/en/pyoxidizer-0.20.0/oxidized_importer_resource_files.html).

### Context information (for bug reports)

* Output of `pyinstaller --version`: ```6.11.1```
* Version of Python: 3.11-3.13
* Platform: Linux Ubuntu 22.04
* How you installed Python: 
```yaml
jobs:
  Build:
    runs-on: ${{ matrix.os }}
    strategy:
      fail-fast: false
      matrix:
        os: [windows-latest, ubuntu-22.04]
        python-version: ["3.11", "3.12", "3.13"]
    steps:
      - uses: actions/checkout@v4
      - name: Set up uv for Python ${{ matrix.python-version }}
        uses: astral-sh/setup-uv@v5
        with:
          enable-cache: true
          cache-dependency-glob: "uv.lock"
          python-version: ${{ matrix.python-version }}
```
* Did you also try this on another platform? Does it work there?
Yes. It works fine on Windows and my local WSL2 (Ubuntu) instance

* try the latest development version, using the following command:

```shell
pip install https://github.com/pyinstaller/pyinstaller/archive/develop.zip
```

* follow *all* the instructions in our "If Things Go Wrong" Guide
  (https://github.com/pyinstaller/pyinstaller/wiki/If-Things-Go-Wrong) and

### Make sure [everything is packaged correctly](https://github.com/pyinstaller/pyinstaller/wiki/How-to-Report-Bugs#make-sure-everything-is-packaged-correctly)

  * [x] start with clean installation
  * [x] use the latest development version
  * [N/A] Run your frozen program **from a command window (shell)** — instead of double-clicking on it
  * [x] Package your program in **--onedir mode**
  * [x] Package **without UPX**, say: use the option `--noupx` or set `upx=False` in your .spec-file
  * [x] Repackage you application in **verbose/debug mode**. For this, pass the option `--debug` to `pyi-makespec` or `pyinstaller` or use `EXE(..., debug=1, ...)` in your .spec file.


### A minimal example program which shows the error
