ci-license-scan: Sort list of fixup files
On commit 419f9c7c duplicate files entries were removed to have a cleaner report. However, this change caused that different passes of the scanner resulted in file lists with different ordering. Even if results provide same information, the fact the ordering is different cause that our CI machinery triggers a new commit to update the scan report.
Fix the issue by sorting the list of files in the copyright fixups.
