package/luarocks: luajit is now detected automatically by luarocks

Since luarocks commit
https://github.com/luarocks/luarocks/commit/ffab9f32698431bb901b786460e4695806ebcf30,
available since luarocks v3.2.0, LuaJIT is now detected
automatically. It is therefore no longer necessary to explicitly
indicate in lua_interpreter that LuaJIT is used.
