[JENKINS-49068] Reuse GitHub branch job's credentials for fetching shared library

Let's say I have 2 private GitHub repositories, both requiring the same credentials for access. If Jenkins is already building one of the repositories (e.g. with GitHub Branch Source Plugin), it would be very convenient if @​Library('github.com/owner/other-repo) _ would just work for fetching shared code from the other repository.
