[issue43113] os.posix_spawn errors with wrong information when shebang points to not-existing file

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

> FileNotFoundError: [Errno 2] No such file or directory: './demo'

'./demo' filename is set with the following code in Modules/posixmodule.c:

    if (err_code) {
        errno = err_code;
        PyErr_SetFromErrnoWithFilenameObject(PyExc_OSError, path->object);
        goto exit;
    }

I understand that Tomas wants to raise the OSError with no filename.

I add Pablo and Joannah in the loop, they worked on exposing posix_spawn function in Python.
