Title: fix use of arg in ltn12

`arg` is not part of Lua 5.1 and hence no longer works in Lua 5.2 or LuaJIT with its default compilation options.

Note that `arg` is apparently used in other parts of the codebase, but I have only hit this issue in ltn12 so far. If you think this fix is correct I can git a try at hunting use of `arg` in other places.
