disable cvv build standard

Since the cvv module doesn't build at all and fixing it doesn't seems straightforward, but a future thing, I suggest disabling that module by default, like done with the world module. All other modules built just fine on the 3.0 as the version I tested today with this install command

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_CUBLAS=ON -D WITH_CUFFT=ON -D WITH_EIGEN=ON -D WITH_OPENGL=ON -D WITH_QT=ON -D WITH_TBB=ON -D BUILD_DOCS=OFF -D BUILD_EXAMPLES=OFF -D BUILD_TESTS=OFF -D CUDA_ARCH_BIN="3.0" -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules/ ..
