Revert "Temporarily take iOS x64 out of the CQ."

This reverts commit 1d26240fe97bee68b3ed3c53ddd19b7611a4fa5c.

Reason for revert: The bot configs are now fixed.

Original change's description:
> Temporarily take iOS x64 out of the CQ.
> 
> They are failing when installing the test app; the Info.plist misses
> CFBundleShortVersionString. I have no idea why this happens, presumably
> it is a new requirement of MacOS 10.4?
> 
> I think it's OK to take these out for now since we still have plenty
> of iOS coverage and investigate the above issue.
