package/opencv: define modules inter-dependencies

OpenCV allows to enable/disable the selection of modules (a.k.a.
opencv libraries). These modules depend one on the others; these
dependencies are already handled by the build-system (CMake).

However, the way we handled them in Buildroot was not really clean.
For each opencv module, there is a kconfig option, but we forced the
corresponding CMake config option without checking for the modules'
dependencies.
For further details about the issues this situation was causing, refer
to this discussion [1].

This patch replicates the modules' dependency relations in the
Config.in, so that the selection of the user will actually be built.
This changes completes this work [2].
