Subject: [PATCH] gitlab-ci: Only run docker-image stage if relevant source
 files change

Otherwise there's normally no need to run it. It will also run when a
new branch is created, which ensures that the docker image always exists
(e.g. in a newly forked repository).

Inspired by https://gitlab.freedesktop.org/mesa/mesa/merge_requests/143
