Fixup formatting 🔧 of "list_controllers.py" and do not check formating on build stage.

[destogl]

I also made output a bit simpler to read by intending also the "required"/"claimed" - string

joint_state_broadcaster[joint_state_broadcaster/JointStateBroadcaster] unconfigured
        claimed interfaces:
        required command interfaces:
        required state interfaces:
                joint1/position
                joint2/position
                tcp_fts_sensor/force.x
                tcp_fts_sensor/force.y
                tcp_fts_sensor/force.z
                tcp_fts_sensor/torque.x
                tcp_fts_sensor/torque.y
                tcp_fts_sensor/torque.z
