[infra] Allow RubberStamper to revert public API changes

RubberStamper won't +1 changes that modify include/*.h or other
non-trivial files, unless they are a clean revert.

Even after this change, someone on include/OWNERS will be needed
to verify actual API changes, one won't be able to just use
rubber-stamper to bypass the check.
