Subject: [PATCH] fix: convert %lua_provides to pure Lua for better control

Converts the logic within the %lua_provides macro from a
multi-line string of RPM macros to native Lua code. This allows
for more robust conditional logic, especially when checking for
default Lua versions and handling provides/obsoletes.

+- Finally broke %lua_provides to be working. I got stumped by the
+  craziness of rpm which runs Lua interpreter with locales and
+  crazy reformatting of integers.
