Adam Comella b050b6906d BREAKING: iOS: Fix case sensitivity build warning in Xcode 8.3
Summary:
**Breaking Change Notes**

To adapt to the breaking change, app developers that are consuming React Native through CocoaPods must update their Podfile to refer to yoga with a lowercase "y". In other words:

    pod 'Yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

Must be changed to (note the lowercase "y"):

    pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

**Symptom**

If you consume React Native as a CocoaPod and consume a third-party React Native module not as a CocoaPod, you will receive a `nonportable-include-path` warning in Xcode >= 8.3.

**Details**

Xcode 8.3 introduced -Wnonportable-include-path which triggers if you import a header using different casing than the path to the header on disk. This triggers when consuming React Native as a CocoaPod from a library that isn't a CocoaPod. React Native imports Yoga using paths like this:

    #import <yoga/Yoga.h>

Which means Yoga's headers are expected to be located in a directory called "yoga" with a lowercase "y". However, when React Native is a CocoaPod the Yoga headers for non-CocoaPods end up in the directory "$(BUILT_PRODUCTS_DIR)/Yoga".

To fix this such that Yoga's headers end up in "$(BUILT_PRODUCTS_DIR)/yoga" (note the lowercase "y"), I've changed Yoga's podspec name to have a lowercase "y".

**Test Plan**

Created a test app where React Native is consumed as a CocoaPod. Added the react-native-maps library to the project and configured it to not be consumed through CocoaPods. Verified that the app compiles properly without the `nonportable-include-path` warnings.
