compositor: authorize new screenshooter protocol

Browse Source 
This is necessary in order to convert clients/screenshot.c into the
protocol.

We authorize a client the same way as before: if the wl_client is the
one we spawned, it's allowed.

Allowing screenshots on --debug was authorized by an earlier patch in
compositor/main.c.
