rtla/osnoise: Use pretty formatting only on interactive tty
osnoise top performs background/font color formatting that could make the text output confusing if not on a terminal. Use the changes from commit f5c0cdad6684a ("rtla/timerlat: Use pretty formatting only on interactive tty") as an inspiration to fix this problem. Apply the formatting only if running on a tty, and not in quiet mode.
