tests/CMakeLists: Use same dependencies as src/ (#163)

* tests/CMakeFiles: Use FFMpeg like src/

* Use system jsoncpp in tests, too

The tests/ build needs to use the same jsoncpp as the src/ build,
or tests in Clip_Tests.cpp can fail.

* Don't show FFMpeg version messages in tests/

Displaying the version-number messages twice seems like overkill
