output/kms: Make winsys_id unique

Browse Source 
We were using the connector_id for the winsys_id, but different
devices could have connectors with the same id. Since we use
winsys_id to uniquely identify outputs, use both the connector
id and the device id to avoid having outputs with the same id.
