tools/power turbostat: add --out option for saving output in a file 

By default...

Turbostat --debug gconfiguration info goes to stderr.

In FORK mode, turbostat statistics go to stderr.

In PERIODIC mode, turbostat statistics go to stdout.

These defaults do not change, but an option "--out file"
will send all output above only to the specified file.

Periodic output goes to stdout, by default, unless --out is used to specify an output file.
The 5-second interval can be changed with th "-i sec" option.

If turbostat is invoked with a command, it will fork that command

and output the statistics gathered after the command exits.
In this case, turbostat output goes to stderr, by default.
Output can instead be saved to a file using the --out option.
eg. Here a cycle soaker is run on 1 CPU (see %c0) for a few seconds
