Revert 288164 "Roll gtest and gmock DEPS."

Suspected to have broken the Chrome Win build:

c:\b\build\slave\google-chrome-rel-win\build\src\base\numerics\safe_numerics_unittest.cc(577) : error C2220: warning treated as error - no 'object' file generated
c:\b\build\slave\google-chrome-rel-win\build\src\base\numerics\safe_numerics_unittest.cc(577) : warning C4756: overflow in constant arithmetic

> Roll gtest and gmock DEPS.
> 
> These DEPS have not been updated for ~2 years, so there is a good chance
> something will blow up. Due to interdependancy between the repos,
> rolling gtest required gmock also be rolled.
> 
> BUG=none
