I'm seeing ninja lint fail on the new 3-line "shim" files because they are so short that the license check is accessing an element past the end of the lines List. That can be "fixed" a few ways:

including the license in those trivial comment only shim files.

skipping the check for short files

continuing to check them, but check the length first so they merely fail the check.

Proposed fix:

-If something is less than 3 lines long, skip the SSPL disclaimer check.-
Add the license everywhere.

Side fix: when the linter throws, we should report the filename that failed regardless.
