Allow OBS_REPOSITORIES to be a space separated list

Filter out values not found in OBS_REPOSITORIES when retrieving binaries.

I'm assuming OBS_REPOSITORIES should allow multiple values separated by a space (default rebuild).

The sed call replaces groups of spaces with | but this means leading and tailing spaces aren't caught, "default " would become "default|" which would result in "^ " matching any line starting with a space. I'm not sure how much this matters. Is there a simpler way to achieve this?

I'm planning changing obs-gitlab-runner to only trigger builds for repos listed in OBS_REPOSITORIES.

It is better to just rename the variable to OBS_REPOSITORY for now, we do not actually have the need to monitor multiple repositories in the Apertis packaging pipeline so let's keep as simple as possible. :D
