Test: lint_off waiver for missing file/module not working

[paul-demo]

This worked in Verilator v5.024 to waive missing modules when linting. I check the equivalent example on 5.024 using the older .pl test regress style and the same .vlt file. I believe it broke in 5.028, based on reviewing the relevant commit history. But, I've also now tested it at mainline (2025.05.29, so that is v5.037 I think) and it is now broken and results in an error -- basically the waiver was not respected.
