Subject: [PATCH 1/2] Allow Invoking `zstd --list` When `stdin` is not a `tty`
Also now returns an error when no inputs are given.
New proposed behavior:
```
felix@odin:~/prog/zstd (list-stdin-check)$ ./zstd -l; echo $?
No files given
1
felix@odin:~/prog/zstd (list-stdin-check)$ ./zstd -l Makefile.zst; echo $?

felix@odin:~/prog/zstd (list-stdin-check)$ ./zstd -l <Makefile.zst; echo $?
zstd: --list does not support reading from standard input
No files given
