Backport v2022<-v2023dev3: ci-license-scan: Allow copyrights with control chars
Backport !268 (merged)
Currently ci-license-scan tries to validate the copyright by running some checks, since in some cases the scanner outputs binary data. However, these checks filter valid copyrights, for instance those containing \t or \n.
Fix the issue by relaxing the checks to allow some control characters.
