LOG: [LLD] Improve the lit tests added by 272bd6f9cc86bf6b4dd6bd51e85c46db10e8b86a

The `cp` command will copy the permission bits from the original file to
the new one, which will cause permission denied (no written access) for the
following "echo" command in some system.

Switch to use `cat` which is more robust.
