fix yoga build issue Could not find yoga:libfb:unspecified.

Summary:
Fixes the yoga build 1:15:0 build issue

    Could not find yoga:libfb:unspecified.
    Required by:
    project :app > com.facebook.yoga:yoga:1.15.0

libfb dependency was added to solve import issue in YogaPhantomJNIRefs but since we don't have that file now in codebase , it will not be a problem.
