Use appropriate capitalization of Xcode

Summary:
[Xcode](https://developer.apple.com/xcode/) is spelled with a lowercase `c`. 😄

**Test plan (required)**

ctrl-f project for `XCode`, case sensitive, find-and-replace with `Xcode`.

Make sure tests pass on both Travis and Circle CI.
Closes https://github.com/facebook/react-native/pull/12572
