Fix negative zoomScale in RTL

Summary: Changelog: [iOS][Fixed] - When in an RTL locale on iOS, e.nativeEvent.zoomScale is -1. This seems to cause erratic blank spaces that don't recover as you scroll. Taking Math.abs of the value fixes it. Blame: D36169686 (13a72e0) Differential Revision: D36468390 fbshipit-source-id: f18244f1421fc1ccbb0d1035df8a7c6de10ccf62
