rdio-scanner: Fix systemID to match the datatype used in rdio-scanner (…

…#860)

rdio-scanner uses a Go uint (uint32_t is the C equivalent) to store the system ID: https://github.com/chuot/rdio-scanner/blob/c9c4ea4530f906dc2f1a9d67706ca987e5f82131/server/system.go#L29

This also prevents 47460b1 from making this doc wrong, as the current state requires a string: https://github.com/robotastic/trunk-recorder/blob/713049ad540423392db5ed8b7fba3507bb0c0fea/docs/Plugins.md?plain=1#L50
