[igt-dev] [PATCH i-g-t] gitlab-ci: Build Docker images if Dockerfiles have changed

[Arkadiusz Hiler]

The jobs that build container images and upload them to the registry do
not have to be manual any longer. By leveraging the new only-changes
feature, we can trigger those jobs conditionally on any alterations to
the Dockerfiles.
