twister: Set stdin explicitly on stty calls
stty operates on the file descriptor from stdin, but we want to operate on stdout. If stdin and stdout are not the same tty then stty prints an error. Redirect stdout to stdin for stty calls. Tested by running twister -T tests/subsys/shell </dev/null Signed-off-by: Jeremy Bettis <jbettis@google.com>
