perf stat: Flush output after each line in interval mode
When interval mode is outputting to a pipe, each measurement should be
flushed individually, so that the reader sees it timely.
With a terminal each line is automatically flushed by stdio, but that is
disabled with non terminal output.
Simply fflush output after each time interval
