Merge #13496: Test: Harden lint-filenames.sh

927e1150bc207181f7d5b0948e87d04b737a1c27 Test: Harden lint-filenames.sh (wodry)

Pull request description:

  - This fixes that only files with lower case file name suffix where found before, which contradicted the Regex to find uppercase characters in file names (including suffixes I guess).
  - `--full-name` switch was added to git ls-files, to define that the found file always includes it's full path in the git project.
  - since we know now that the file name includes the full path, we can harden the Regex to exclude the  secp256k1 and univalue sub folders.
  - use backslash line break to make code easier to read and avoid too long line.
