image-copy: Use abstraction that's now provided by Smithay

This doesn't change much, since the Smithay implementation is based on
the `cosmic-comp` version, but made more generic. We provide our own
implementation for our workspace capture protocol, but otherwise Smithay
handles the boilerplate now.

This should not cause any change in behavior.
