ext: Build googlemock with googletest

googlemock needs to be built together with googletest. This patch
is enabling it by doing the following things

* Moving googletest and googlemock under the same top level directory,
  so that we have a single SConscript for building them.
  This also matches googletest directory structure:
  googletest
      |_googletest
      |_googlemock

* Adding a shared SConscript which is building gmock and gtest as libgtest
* Removing googletest/SConscript
