Work around the broken way CocoaPods/Xcode deals with header maps

Summary:
See https://github.com/facebook/react-native/issues/14326 for the bug
this fixes.  This is a pretty ugly hack to work around what I think is
a CP bug.  Since the C++ dependencies are only needed to build RN
itself, and not applications, don't the conflicting headers as source
files.  Instead, use preserve_paths to get them unpacked into the
source tree under Pods/<Pod>, and arrange for them to get used with
HEADER_SEARCH_PATHS.  This keeps them out of the project, so they
don't get included in the header map, and other (badly structured)
projects don't get confused.
