Need to add deps entry for upload_progress_tracker.(cc|h).  Perhaps we should be
separating out the files that are legal to depend on into another (sub)directory
(Or those that aren't).  Then we don't need a per-file whitelist of stuff in
content/browser/loader/.  Not suggesting it for this CL.

Done.
