BUG: remove numpy.f2py from excludedimports

[yanwic]

We noticed that PyInstaller fails to correctly bundle our application when using SciPy 1.13.1 & NumPy 2.0.0

Scipy ends up trying to import numpy.f2py when using optimize.root_scalar resulting in a runtime ModuleNotFoundError:

ModuleNotFoundError: No module named 'numpy.f2py'

A minimal reproducible script would be the following:

from scipy import optimize
optimize.root_scalar(lambda x: x,x0=1)

Tested with these dependencies:

python = ">=3.10,<3.13"
numpy = "^2.0.0"
pyinstaller = "^6.8.0"
scipy = "^1.13.1"

For a bit of context (since we've been looking into this over at PyInstaller as well): in numpy 2.0.0, f2py submodule was added to __all__ attribute of the numpy module. Therefore, excluding numpy.f2py in the PyInstaller hook breaks code that performs

from numpy import *

Most notable example of this is array_api_compat.numpy from https://github.com/data-apis/array-api-compat, which is used by scipy as scipy._lib.array_api_compat (as seen in the OP's traceback).

(The same would have happened with numpy.distutils, except it was not added to __all__ due to deprecation).
