move jenkins dependencies to defaults for overriding

Ansible variable hierarchy gives highest precedence to role variables.
Having jenkins repo paths in role variables makes it difficult to
override them from outside the role itself. Moving these variables into
defaults allow for overriding in group_vars or inside another role that
imports ansible-jenkins as a dependency.
