Until now we had two different protocol extensions: one for the test suite screenshooter and other for the screenshooter client. As they are identical and this won't change, make the test suite use the same protocol that the screenshooter client uses. Besides the cleanup, this change will also allow us to use the DRM writeback screenshooter in the test suite, as the test suite implementation is hardcoded to use a renderer based screenshooter.
