Added rtt_ros_integration and rtt_geometry to hydro/release.yaml

Added [rtt_ros_integration](https://github.com/orocos/rtt_ros_integration.git) and [rtt_geometry](https://github.com/orocos/rtt_geometry.git) repositories to `hydro/release.yaml` without a version number for pre-release testing and to enable rosdep to resolve ROS package to binary package names.
