Unfortunately, these bots don't actually exist, which is why we have the hack of
mapping the ports onto the only bot that does.

Arguably we should just not attempt to look at the deps bots at all in
update-flaky-tests, but it's probably not worth changing at this point
(hopefully the Blink/Chromium merge will happen soon enough).

I see. OK. I updated the CL to just add a comment.
