python313Packages.pysmartdl: fix tests

python 3.13 drops `unittest.makeSuite` but provides an easy to use
alternative under `unittest.TestLoader`.
this alternative is old enough to work in all python 3 versions that
nixpkgs contains (currently 9..13), might aswell use it for all of them

even if it really doesn't matter functionally, `pythonAtLeast` would
introduce unnecessary differences between the packages built for
different python versions
