Add CMake option YAML_USE_SYSTEM_GTEST to use system googletest if available. (#1035)

Browse Source 
There is no need to use the embedded gtest code copy in Linux systems, if they already provide the googletest framework system-wide.
Search for it, and fallback to the embedded one if the system one is not detected.
