Subject: [PATCH] Resurrect long since broken Lua library path
LUA_PATH global variable is not consulted when loading libraries in
Lua >= 5.1, package.path has replaced it. Rpm's Lua library path
was always supposed to be /usr/lib/rpm/lua/ but this has been broken
for the last ten years or so, oops. Make the directory a first-class
citizen: create it on install, add a macro for it, make it actually
work and ensure it stays that way by adding a test for it.
