LOG: [llvm][llvm-lit] Correct description of --use-unique-output-file-name

The initial version of this feature would use the output file name
if it could, but in switching to temp files I forgot to replicate that
behaviour.

What happens now is we always use a tempfile name and the output
path is a template for that. I think the current behaviour
still makes sense so I'm just correcting the documentation.
