package/lua/5.1.5: add patch for CVE-2014-5461

Browse Source 
This CVE is specific for the version 5.1.5 still present in Buildroot.
It has been fixed in 5.2.3 and thereby doesn't affects the other
versions available in Buildroot.

- CVE-2014-5461

Buffer overflow in the vararg functions in ldo.c in Lua 5.1 through
5.2.x before 5.2.3 allows context-dependent attackers to cause a denial
of service (crash) via a small number of arguments to a function with a
large number of fixed arguments.

  - https://security-tracker.debian.org/tracker/CVE-2014-5461
  - https://udd.debian.org/patches.cgi?src=lua5.1&version=5.1.5-11

A patch present in Debian is used to address this vulnerability.
