LOG: [llvm][llvm-lit] Hide --use-unique-output-file-name from --help (#114812)

I was too hasty landing an option whose only known use at this time is
LLVM's own CI.

We may be able to remove it before the next branch that would be the
next llvm-lit release outside of llvm, but the timing may not work out.

So I am hiding the option in case that were to happen.
