More details in log when temporary directory can't be removed

Sometimes the temporary directory can be removed. The log contains something like this:

… Deinitializing Setup.

… Failed to remove temporary directory: C:\Users\…\AppData\Local\Temp\is-U4EUZLD8E5.tmp

… Log closed.

But you have no information, which file is blocking the removal if you don’t inspect that folder immediately. A more verbose output that lists the affected files would be helpful.
