Subject: [PATCH] updater: workaround CPython bug 128211

Python 3.13 list comprehensions are buggy [1]: [i for i in x] calls
iter(iter(x)) instead of just iter(x).  Work around the bug by having
UpdateListIter have a __iter__(self) that just returns self.  This is
the same thing that the standard library does:

    x = iter([])
    print(x is iter(x))

prints True.
