Re-add the CQ directory to chrome/trunk/tools.

Re-add the CQ directory to chrome/trunk/tools.

This directory is still pulled by DEPS and is in official Buildspecs.
Re-add it for now until we can remove it from all of those.

Hey, that's why the svn lock idea wasn't such a bad idea after all. :)

lgtm

Yep! Though it wouldn't have actually found this, and we would have just run
into the problem in a month when I switched the lock to a removal :)

FYI, I think the only place this is referenced is
svn://svn.chromium.org/chrome/trunk/tools/build/DEPS. It was added years ago,
and I don't know of anything that actually cares about it (or cares enough to
not be broken by it just having a placeholder file now). I'm quite sure it was
never important to the official buildspecs, which just bring it in because it's
there, not because they use it. Probably should just be removed.
