Replace import for WebRTC headers.

WebRTC iOS SDK removed placeholder for ObjC headers in
https://source.chromium.org/chromium/_/webrtc/src.git/+/6bfad33fd866e682c871c2ef2172b70b609593d1.
OWT imports both modified WebRTC headers from WebRTC framework and
original headers from source code, which results duplicated definitions.
Running :s/#import <WebRTC/(.*\.h)>/#import "$1"/g to avoid import
headers from WebRTC framework. A follow up change will modify public OWT
headers back to import WebRTC framework during packaging.
