driver-manager: fix E0382 — clone Arc for the second listener closure

spawn_unified_listener takes two move closures that both capture scheme_for_events
(bound_device_pairs provider + the Aer event handler calling dispatch_recovery).
The first closure moved the Arc, so the second could not use it ("the type Arc
does not implement Copy", main.rs:390). Clone the Arc for the bound-pairs closure
so each owns its own handle (the rustc-suggested fix). Sole remaining compile
blocker for the redbear-full ISO.
