perf docs: Correct typo of event_sources

The sysfs directory is called event_source.

Before:

  $ ls -la /sys/bus/event_sources/devices/cpu/format/
  ls: cannot access '/sys/bus/event_sources/devices/cpu/format/': No such file or directory
  $

After:

  $ ls -la /sys/bus/event_source/devices/cpu/format/
  total 0
