Fix partial availability warnings on Mac AppRTCMobile

The partial availability problem aries from the	fact that the minimum
supported OSX version is set to 10.9, but AppRTCMobile is using
functions available only in 10.10 and later. The minimum OSX version is
set as a declare_args() in build/config/mac/mac_sdk.gni, which makes it
difficult to override for just the AppRTCMobile target in WebRTC.

Instead, this CL solves the problem for now by removing the usage of the
10.10 function, which is trivial.

Also, the flag:
'extra_substitutions = [ "MACOSX_DEPLOYMENT_TARGET=10.8" ]'
is removed since it has no effect.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others. This page is maintained by the Google Chrome team.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
