Move wheel-build scripts out of jenkins/scripts

We only need the three wheel-X scripts from jenkins/scripts and need
them only for the playbook and its roles. Move the scripts in the
roles directory and copy them only if needed - using the scripts module.

Remove copying of complete jenkins/script for this playbook using the
role legacy-copy-project-config-scripts, it's not needed anymore.
