It was not producing any results on presubmit for 2 reasons:
- The list of modified GN files contained relative paths but the list

- The root directory was not passed to the script and the path of the
first file substituted it.
Fix potential problem with using unescaped names in a regex.
Blacklist testdata directory with intentionally bad BUILD.gn files.
