perf stat: Remove --per-thread pid/tid limitation
Currently, if we execute 'perf stat --per-thread' without specifying
pid/tid, perf will return error.
root@skl:/tmp# perf stat --per-thread
The --per-thread option is only available when monitoring via -p -t options.
-p, --pid <pid> stat events on existing process id
-t, --tid <tid> stat events on existing thread id
This patch removes this limitation. If no pid/tid specified, it returns
all threads (get threads from /proc).
Note that it doesn't support cpu_list yet so if it's a cpu_list case,
then skip.
