tools/power turbostat: return the exit status of a command 



turbostat failed to return a non-zero exit status even though the
supplied command (turbostat <command>) failed.  Currently when turbostat
forks a command it returns zero instead of the actual exit status of the
command.  Modify the code to return the exit status.
