tools/power turbostat: allow running without cpu0
Linux-3.7 added CONFIG_BOOTPARAM_HOTPLUG_CPU0,
allowing systems to offline cpu0.
But when cpu0 is offline, turbostat will not run:
# turbostat ls
turbostat: no /dev/cpu/0/msr
This patch replaces the hard-coded use of cpu0 in turbostat
with the current cpu, allowing it to run without a cpu0.
Fewer cross-calls may also be needed due to use of current cpu,
though this hard-coding was used only for the --debug preamble.
