selftests/timers: Add missing fflush(stdout) calls
When running under a pipe, some timer tests would not report output in real-time because stdout flushes were missing after printf()s that lacked a newline. This adds them to restore real-time status output that humans can enjoy. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
