Tom Finegan e569ab0f7c webm2pes/ts: Fix gcc build.
Fix the build and tidy up a couple things along the way.

- Add -std=c++11 to CMakeLists.txt CXX flags.
- Add missing include to libwebm_utils.h (<memory>).
- Setup CMAKE_CXX_FLAGS properly (allow user override).
- Add missing URL for gtest repo to README.libwebm.
