perf record: Fix the profiling of existing pid or whole box
Perf record bails if no command argument is provided, so you can't use
naked -a or -p to profile a running task or the whole box.
Allow foreground profiling of an existing pid or the entire system.
[ Impact: fix command option handling bug ]
