The symbol visibility=hidden flag was only being applied to C compilation, so plugins implemented in C++ would leak extra symbols than the 2 _get_desc() and _register(). That also showed that the gst-libs opencv C++ lib was not marking symbols for export correctly because the BUILDING_GST_OPENCV define wasn't in the C++ args, so fix that too.
