Accepting request 1299226 from home:mcalabkova:branches:devel:languages:python

- 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
