Documentation/trace/events.txt: Remove obsolete sched_signal_send.
'sched_signal_send' doesn't exist in the kernel now. Replace it
with 'signal_generate' so that the example in events.txt can be
executed successfully.
I also change some /debug to /sys/kernel/debug which is debugfs'
default mount directory now(similar to commit 52ad51e).
