erl_prim_loader: Avoid making absolute paths
We don't need absolute paths unless we are dealing with archives. Since it is not free to turn a relative path absolute (we will need a call to prim_file to fetch the current directory), it's better to delay the call to absname/1 until we are sure it's needed.
