servo: Merge #7692 - Raise max length error over 120 chars not at 120 chars. python/tidy.py (from ddrmanxbxfr:TidyMaxLineOver120); r=nox

This is a follow up of issue : Tidy has an off-by-one error #7686

It allows to raise the max length error when line is over than 120 not at 120 specifically.

Thanks for looking into it.
