Documentation: sched_ext: fix events sysfs path and show_state example

Browse Source 
The events file is under the scheduler's sysfs kobject
(/sys/kernel/sched_ext/root/events for the root scheduler), not the
nonexistent "<scheduler-name>/events" path. Also add the missing "aborting"
line to the scx_show_state.py example.
