[gimp/wip/Jehan/more-CI-build: 16/17] gitlab-ci: set GIT_DEPTH to 1.

[Jehan <jehanp src gnome org>]

commit aa611bea84f7c192bf8427ae5e82a6e00e8ab3e0
Author: Jehan <jehan girinstud io>
Date:   Tue Oct 1 20:36:09 2019 +0200

    gitlab-ci: set GIT_DEPTH to 1.
    
    We don't need to pull 5 commits of history. Only the HEAD of the
    selected branch is needed.
    Also define it globally rather than re-defining it in every job to the
    same value.
