Natives with different versions contained in JAR files

[jcuda]

The build process currently collects all libraries that are contained in the jcuda/nativeLibraries directory and puts them into the jcuda-natives JAR file. If the directory contains libraries with an older version number, they are also included in the JAR. This has to be fixed, either by adding a step to delete the older libraries, or preferably (because far less invasive), by filtering the libraries at https://github.com/jcuda/jcuda/blob/89299bc1140f41348a4fea029e3085955074b1da/pom.xml#L40 based on the current version number.
