xtables-addons: Avoid redefinition of SHRT_MAX in lua packet script

Patch Lua packet script defines SHRT_MAX which is already defined in <linux/kernel.h> and
is included indirectly by lauxlib.h. Fix the redefintion as it leads to compile failure
on systems which treat macro redefinition as an error
