Minor 5.4 bytecode verification nitpick

[Sergey Zakharchenko <doublef.mobile@...>]

Hello list,

The luai_verifycode call contains a reference to 'buff', which isn't
defined anywhere:

https://github.com/lua/lua/blob/69e84805e48b0253007bd0daf481ce7955367d73/lundump.c#L315

It's certainly possible to ignore an argument in a luai_verifycode
macro definition; just wondering what it was supposed to mean.

Best regards,
