avdevice/decklink: Fix compilation of module on OSX
Clang applies the missing-prototypes warning on C++ files, whereas gcc only applies it to C. As a result, the decklink_common.cpp file fails to build because of missing prototypes in DecklinkDispatch.cpp (which is #included by decklink_common.cpp). We don't want to change the actual Blackmagic SDK sources, so suppress the warning just for that one #include.
