[patch] hackbench: flush buffers before fork

From: Nathan Lynch

Here's a fixlet for the hackbench program found at

http://people.redhat.com/mingo/cfs-scheduler/tools/hackbench.c

When redirecting hackbench output I am seeing multiple copies of the
"Running with %d*40 (== %d) tasks" line. Need to flush the buffered
output before forking.
