screencopy-v1: fail concurrent capture_output requests

Browse source 
Send the failed event immediately when a client sends capture_output
or capture_output_region for an output that already has a live frame
owned by that client.

Enforces one frame per (client, output) pair, matching ext-image-copy-
capture-v1's create_frame restriction without adding a new error code
or bumping the interface version.
