Subject: [PATCH] fix arc drawing when sweep >= 360

Summary:
I hit this issue in my own component https://github.com/nihgwu/react-native-pie, and find this https://stackoverflow.com/questions/19383842/weird-behaviour-in-drawing-a-ring-using-path-arcto-in-android, after this change, it looks exactly the same on both Android and iOS
Closes https://github.com/facebook/react-native/pull/15042
