gtest, gmock: pull older versions via DEPS that don’t require C++11 library support

gtest, gmock: pull older versions via DEPS that don’t require C++11
library support.

When building with support for Mac OS X 10.6, C++11 library support is
not available, because Mac OS X uses libc++ for C++11 support, and Mac
OS X 10.6 does not provide libc++ as a runtime library. gtest and gmock
have a hard time distinguishing between C++11 language and library
support (which is not really their fault, having one but not the other
is an odd situation). The currently-released trunk versions of gtest and
gmock do not work in this configuration. I’ve submitted patches upstream
to fix this, but they may take a while to make it to the released
verions. For now, it’s fine to roll gtest and gmock back to versions
from December 2013 that do work cleanly with C++11 language support but
only C++03 library support.

TEST=Compile and run all tests in both 10.6 and native builds
