tools/kvm_stat: use canonical ftrace path
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing A comment in kvm_stat still refers to this older debugfs path, so let's update it to avoid confusion.

All available events have directories under

+ /sys/kernel/tracing/events/ which export information
about the specific event. Therefore, listing the dirs gives us
a list of all available events.
