my_activity: Skip Rietveld cookie check if not found.

ChromiumOS only developers don't always have a Chromium checkout and
a Rietveld cookie file (~/.codereview_upload_cookies) with the auth
keys. This patch proceeds with the activity lookup from other
services such as Gerrit and GoB if there's no Rietveld cookie
present, displaying an error message when this happens.

BUG=chromium:316961
TEST=Remove ~/.codereview_upload_cookies and ran my_activity. ChromeOS activity listed.

This is a fix for ChromeOS only users reported by two users. Apparently we
silently fail if you have never run "git cl upload" before :) which makes sense
if you don't develop code for chromium but just chromiumos.

Please review :)
