Koji config adjustment

[Pierre-Yves Chibon]

Good Morning Everyone,

Trying to finish https://pagure.io/releng/issue/6671 I tried to adjust the koji
configuration as needed.
Attached is the corresponding patch which I would prefer someone with more
knowledge of koji than me to review and/or apply (and even deploy if possible).

Thanks for your help,

Pierre

First, applied cosmetic change to use newlines for separate instead of just spaces (only
in staging):

Builds still work:  https://koji.stg.fedoraproject.org/koji/taskinfo?taskID=90060787

OK, this works in staging now.

Here's the patch:

https://infrastructure.fedoraproject.org/cgit/ansible.git/commit/?id=0736...

And verified that:

- I was allowed to build from my fork before applying it (bad!): 
https://koji.stg.fedoraproject.org/koji/taskinfo?taskID=90061005
- I was disallowed from building from my fork after applying it (good!): 
https://koji.stg.fedoraproject.org/koji/taskinfo?taskID=90061043
- Regular builds from the primary non-fork repos still worked afterwards:
