[GN] Fix generate Xcode project for macOS to work with Xcode 8.

Overridding ARCHS prevents Xcode 8+ from running the compiled binary
on macOS. In addition avoid hard-coding the version of the SDK to use
(since we do not build with Xcode this value is unused) and instead
mention that the version-less SDK.
