Rename uikit/CSSLayout to CSSLayoutKit.

Summary:
When trying to integrate this into an Xcode project that already included CSSLayout.[c|h], we were getting a linker error.

Upon digging in, I found out that Xcode was becoming confused because the imports of the uikit library and the c library are both `#import <CSSLayout/CSSLayout.h>`. So, it needed a new name.
