lit.py currently allows any substring of `target_triple` to be used as a feature in REQUIRES/UNSUPPORTED/XFAIL. This results in various forms of the OS spread across the tests and is also somewhat confusing since they aren't actually listed in the available features. Modify all OS-related features to use the `OS=` version that Swift adds instead. We can later remove `config.target_triple` so that these don't the non-OS versions don't work in the first place.
