¡Hola!

While rebuilding packages against python 3.15 we found that jpy
produces some errors when used against it. Some of this caught by the
autopkgtest[0].

This is due that some deprecated and removed functions are used:
Py_GetProgramName(), Py_GetPrefix(), Py_GetExecPrefix(),
Py_GetProgramFullPath(), Py_GetPath(), Py_GetPythonHome()

I'm attaching a patch to remove those functions
