Revert of Build in C++11 mode on Unix-like bots.

Revert of Build in C++11 mode on Unix-like bots. (patchset #4 id:60001 of https://codereview.chromium.org/868233008/)

Reason for revert:
Perf-Ubuntu12, and Test-Ubuntu12, Build-Nacl  all too old.

Android and Chrome OS builders look ok.
Android testers look ok.  Chrome OS testers haven't run yet.

Original issue's description:
> Build in C++11 mode on Unix-like bots.
> 
> Mac and Windows bots are already building in C++11 mode.
> This turns on the rest, mostly to see what work remains.
> 
> This will probably break a few bots.  It'd be nice if we could let those
> all come in as red before reverting this so I can see the full list to fix.
