.gitlab-ci.yml: Avoid pulling artifacts for every BuildStream build
We shouldn't download artifacts to the CI workers every time somebody pushes just to throw them away again. This should speed up no-op builds. The functionality is implemented in two shell scripts. Context is here: https://gitlab.com/BuildStream/buildstream/issues/77 It would be possible to do this with a single script, but I wanted to avoid doing any argument parsing code in shell.
