dev-util/weka: add missing rdep on libsvm and the use flag "svm" #565550

Weka only ships a wrapper class for the actual libsvm package. Add a use
flag named "svm" and pull in sci-libs/libsvm[java] for proper SVM support
when the use flag is enabled.

Upstream-URL: https://weka.wikispaces.com/LibSVM

Package-Manager: portage-2.2.20.1
