CvRTrees: setting a random seed

It is necessary to define different random seeds for stability analysis. However, since Vadim's ml refactoring (commit ba3783 from July) rtrees.cpp does not use the global cv::theRNG() any more. A local instance is used instead, which is seeded with a constant value.
