Revert of Emit original solution after gclient sync (https://codereview.chromium.org/348463002/)

Reason for revert:
Breaks well, everything that calls runhooks (which is like everything).  Reverting and revisiting tomorrow.

Original issue's description:
> Emit original solution after gclient sync
> 
> Because we reset .DEPS.git after a checkout, but gclient runhooks still needs
> to use a DEPS file to run hooks, we also want to reset the .gclient file to point
> at the DEPS file.
