tools/power turbostat: Fix unrecognized option '-P'

The '-P' short option (shorthand for --no-perf) is not present in the
optstring of the second call to getopt_long_only(). This results in
the "unrecognized option" error when the tool reaches the main parsing
loop.

Add 'P' to the second getopt_long_only() call to ensure it is
consistently recognized.
