turbostat misses some fields

Hello on my Ubuntu 22.04 system the "turbostat" program does not output all the requested columns, which breaks the parsing of its output at line 1154. You can see in this sample that `GFX%rc6 and Pkg%pc7 are missing:
```
$ TURBO_COLUMNS="CPU%c1,CPU%c6,CPU%c7,GFX%rc6,Pkg%pc2,Pkg%pc3,Pkg%pc6,Pkg%pc7,Pkg%pc8,Pkg%pc9,Pk%pc10,SYS%LPI"
$ sudo ./turbostat --quiet --show "$TURBO_COLUMNS"
CPU%c1 CPU%c6 CPU%c7 Pkg%pc2 Pkg%pc3 Pkg%pc6 Pkg%pc8 Pk%pc10 SYS%LPI

I'm not sure which is the best way to work around this issue
