Lua 5.3 removed deprecated variadic function `arg' parameter

Variadic functions were introduced in 5.0, but the method of accessing
them changed in 5.1. This makes the code incompatible with 5.0 (it is
already incompatible since at least b2b1755), which will be removed
from the build system in a subsequent commit.

Fixes raboof#124. See also raboof#90.
