[3.13] gh-143050: Correct PyLong_FromString() to use _PyLong_Negate() (#145901) (#147437) 
The long_from_string_base() might return a small integer, when the
_pylong.py is used to do conversion.  Hence, we must be careful here to
not smash it "small int" bit by using the _PyLong_FlipSign().

README.txt 

Tests in this directory are compiled into the _testcapi extension.
The main file for the extension is Modules/_testcapimodule.c, which
calls `_PyTestCapi_Init_*` from these functions.

General guideline when writing test code for C API.
* Use Argument Clinic to minimise the amount of boilerplate code.
* Add a newline between the argument spec and the docstring.
* If a test description is needed, make sure the added docstring clearly and succinctly describes purpose of the function.
* DRY, use the clone feature of Argument Clinic.
* Try to avoid adding new interned strings; reuse existing parameter names if possible. Use the `as` feature of Argument Clinic to override the C variable name, if needed.
