This patch changes the test that uses the `cat -e` option to `cat -v` so that the test can be run using lit's internal shell. For `cat`, the `-v` option prints non-printing characters in ^ and M- notation, while the `-e` option adds `$` to the end of lines in addition to printing non-printing characters in ^ and M- notation. This is an alternative patch to https://github.com/llvm/llvm-project/pull/102061, opting to rewrite the test that uses `cat -e` instead of extending support to the `-e` option.
