[libgpiod][PATCH] bindings: python: replace PyModule_AddObjectRef() with PyModule_AddObjectRef()

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

PyModule_AddObjectRef() was added in cpython v3.10 while libgpiod claims
to depend on python v3.9. Replace it with an older variant that steals the
reference to the added object on success.
