update dataflow-gamepad to drive the arm instead of the bench

It now runs joy, teleop and dora-ulite6 with the probe declared and the
console shut, so a pad can be checked against the arm that will actually
move. ROBOT_IP in both arm dataflows points at the bench arm.

The run recipe drops dora up + dora start: dora 1.0.1 refuses to start a
dataflow holding git: nodes from a coordinator, reporting that no build was
run straight after one that succeeded. That costs the file dora topic, which
needs a coordinator to read the wire.
