InstCountCI: Ensure output nasm name doesn't conflict

Pretty sure this is why CI is unhappy. If a test in a different file has
the same name then it is highly likely to conflict when nasm is
generating files and will overwrite and erase, causing CI to break.

Include the incoming json filename as part of the asm keys so it can't
conflict here.
