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).

For example:

A slightly more involved example:

If there is an error in the expression, you'll get an 'Invalid
argument' error when setting it, and the erroneous string along with
an error message can be seen by looking at the filter e.g.:
-# cd /debug/tracing/events/sched/sched_signal_send
+# cd /sys/kernel/debug/tracing/events/signal/signal_generate
# echo "((sig >= 10 && sig < 15) || dsig == 17) && comm != bash" > filter
