tools/power turbostat: return the exit status of a command
[ Upstream commit 2a95496634a017c19641f26f00907af75b962f01 ]
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.
