perf record: Add switch-output time option argument
It's now possible to specify the threshold time for perf.data like:
$ perf record --switch-output=30s ...
Once it's reached, the current data are dumped in to the
perf.data.<timestamp> file and session does on.
$ perf record --switch-output=30s ...
[ perf record: dump data: Woken up 44 times ]
[ perf record: Dump perf.data.2017010213043746 ]
...
The time is expected to be a number with appended unit
character - s/m/h/d.
