Improve informative message in codereview.settings.

In https://codereview.webrtc.org/1389963002 the message
displayed when trying to create a CL from an unsupported
location was improved. However it's confusing for developers
working from a WebRTC checkout if they stand in src/webrtc
when trying to create a CL.
