Mac: Don't show dialogs for debug messages.

They're printed to stderr, and the dialogs are often too high to fit on a (30'') screen.

Just to be clear, what is the problem you are running into Nico? I often find
seeing a DCHECK fail a little more obviously than having it fly by on stderr is
useful.

Several problems:

* The stacks are usually to wide for the message box, so that the message box
contains ugly line breaks
* The stacks are often deep, making the text higher than what fits in the
message box (mostly on my 15' mbp)
* Since DCHECKs terminate the app, "Seeing a DCHECK fly by on stderr" isn't
really what happens – it will be the last thing that's printed on stderr.

I always have to click away the message box since it's unreadable and then look
at stderr. I'd rather only look at stderr.
