[LTP] [PATCH] cpu_hotplug: Add executable file's path

This patch is useless.

For shell-script case, usually, runltp will set environment variables. 
or, you need to set environment variables yourself if not want to use 
runltp(more info see[1]).
For cpuhotplug02 case, we can run as below:
#export LTPROOT=/opt/ltp
#export PATH="$PATH:$LTPROOT/testcases/bin"
#cpuhotplug02.sh -c 1 -l 1
