turbostat: Increase output buffer size to accommodate C8-C10
On platforms with C8-C10 support, the additional C-states cause
turbostat to overrun its output buffer of 128 bytes per CPU. Increase
this to 256 bytes per CPU.
[ As a bugfix, this should go into 3.10; however, since the C8-C10
support didn't go in until after 3.9, this need not go into any stable
kernel. ]
