Fix iOS Bundle layouts (#15669)

In contrast to Mac OS X App bundle layout the iOS one lacks the
Contents/MacOSX structure.  See also the Bundle Structures documentation
in Mac Developer Library:

  https://developer.apple.com/library/mac/documentation/CoreFoundation/Conceptual/CFBundles/BundleTypes/BundleTypes.html

For now detect iOS targets by checking the SDK name/path.
