Bug 1744644 - regenerate build files in third_party/libwebrtc as baseline. r=ng

For some reason, third_party/libwebrtc/rtc_base/timeutils_gn/moz.build was
in an odd state after our final merge where each of the platforms contained
DEFINES["WEBRTC_EXCLUDE_SYSTEM_TIME"] = True
instead of having that define at the top level across all platforms. After
re-running the generation on each platform (macOS/Linux/Win), all platforms
ended with this file in the same state with the define at the top.
