Accepting request 1299348 from devel:languages:python

Forwarded request #1299226 from mcalabkova

- Update to 3.1.3
    * Some method calls with 0 or 1 argument failed to use PyObject_VectorCallMethod().
    * Walrus assignments of literal Python integers could generate invalid C code.
    * cython.pythread_type_lock (also used as fallback for cython.pymutex) could stall
      on heavily contended locks.
    * C string arrays (not pointers) always coerced to the Python default string type,
      even on explicit casts to other string types.
    * Unterminated \N{} character escapes in strings could unrail the parser.
    * An internal C function was not marked as static and leaked a linker symbol.
    * Some Unicode letters were not recognised as lexically valid name parts.
    * Compatibility with PyPy3.8 was lost by accident.
    * The Linux binary wheels of 3.1.2 used SSSE3 CPU instructions which are not
      available on some CPUs.
  - Convert to libalternatives on SLE-16-based and newer systems only
