Apply lua 5.1 patch for CVE-2014-5461

[datMaffin]

I randomly came across your repo. As I did see an unpatched lua 5.1 in the past, I checked, and I believe the patch for CVE-2014-5461, which can be found in various linux distros, like https://sources.debian.org/patches/lua5.1/5.1.5-9/0004-Fix-stack-overflow-in-vararg-functions.patch/ was not applied on your copy:

ziglua/lib/lua-5.1.5/src/ldo.c

Line 277 in 79b1bdb

luaD_checkstack(L, p->maxstacksize);
