cyclictest: Fixed incorrect wakeup reset interface
When we try to run ftrace with cyclictest command of rt-test,
We view the error according to different kernel version.
We need to modify this hard coded interface.
* Directory name of each kernel version
2.6.24.7-rt23 /sys/kernel/debug/tracing/latency_hist/wakeup_latency/reset
2.6.31-rc9-rt9.1 /sys/kernel/debug/tracing/latency_hist/wakeup/reset
2.6.33.7.2-rt30 /sys/kernel/debug/tracing/latency_hist/wakeup/reset
* parsing verification: ./linux-2.6/scripts/checkpatch.pl --> OK
