tools/power turbostat: fix buffer overrun 

turbostat could be terminated by general protection fault on some latest
hardwares which (for example) support 9 levels of C-states and show 18
"tADDED" lines. That bloats the total output and finally causes buffer
overrun.  So let's extend the buffer to avoid this.
