Abhishek Goel f9652d5cae cpupower : Fix header name to read idle state name 
The names of the idle states in the output of cpupower monitor command are
truncated to 4 characters. On POWER9, this creates ambiguity as the states
are named "stop0", "stop1", etc.

root:~# cpupower monitor
              |Idle_Stats
PKG |CORE|CPU | snoo | stop | stop | stop | stop | stop | stop
   0|   0|   0|  0.00|  0.00|  0.00|  0.00|  0.00|  0.00|  1.90

   0|   0|   3|  0.00|  0.00|  0.00|  0.00|  0.00|  0.00|  0.00

This patch modifies the output to print the state name that results in a
legible output. The names will be printed with atmost 1 padding in left.
