Start phasing out internal copy of Lua

- don't build internal copy of Lua
- move 3rd party extensions (posix and rexlib) to toplevel luaext/
  directory, built by default (unless --without-lua specified)
- auto*foo checks for external Lua
- minimal tweaks to lposix.c and rpmlua.c to get them build with Lua 5.1
