Fix #4590: filter rudder_tools on classes.

Until now every files in rudder_tools are copied, for example
.exe files are copied on linux node.
This can be a problem for low bandwith / low disk space devices.
This patch create a list for each platform in order to copy only useful
classes.
In the spirit of a "UNIX" category, I think this should be a "!windows.!android" section.
