test: Add API test for partial pull with pullProgress flag

Browse Source 
Progress reporting in container-libs/image did not update
the progress channel for chunked layers. Add test that builds
a new image with chunked layers, pull it using the REST API
and verify that the progress stream contains events for
partial pulls too.

Depends-on: https://github.com/containers/container-libs/issues/469
