fanotify_mark.2: Clarification about FAN_EVENT_ON_CHILD and new events 

Some of the new event types that were added in v5.1 along with
init flag FAN_REPORT_FID are not eligible for reporting to a
directory watching with FAN_EVENT_ON_CHILD.

Document the events that cannot be generated on children of a
watching parent.
