Fabrice Fontaine 31c68a449e package/opencv3: use external protobuf instead of bundled one 
Since version 3.3.0 and its commit
1c4c58d1b5,
opencv3 bundles its own copy of protobuf. Instead of using the bundled
protobuf library, this commit disables building protobuf
(BUILD_PROTOBUF=OFF) and instead uses the protobuf Buildroot package
(using the WITH_PROTOBUF=ON/OFF option).
