Fix several compilation and installation issues

    Rename targets
      - dynamic_graph/ros/ros_import/wrap -> ros/ros_import/wrap,
      - dynamic_graph/ros/ros_export/wrap -> ros/ros_export/wrap,
      - dynamic_graph/ros/ros_joint_state/wrap -> ros/ros_joint_state/wrap.
    Add missing linking flags to target interpreter.
    Do not redefine PYTHON_SITELIB, use cmake/python.cmake definition.
