DisplayDriverFactory::make() currently returns driver instances in raw pointers. This patch changes it to wrap them in std::unique_ptr.
Note that the various constructors stdout_driver_new(), stdout_sdl_driver_new(), etc. still return raw pointers. The driver code are meant to be externalised into loadable SOs and I'm unsure if we can return std::unique_ptr from there.
