[PATCH] fanotify.7: Fix field name in struct fanotify_event_info_fid

[Matthew House <mattlloydhouse@gmail.com>]

The final field of this struct as defined in include/uapi/linux/fanotify.h
(and as used in the example program) is called handle, not file_handle.
Fix this, and also replace the zero-length array with a flexible array
member to match the definition in the header.

Fixes: 0a4db6dc742d ("fanotify.7, fanotify_init.2, fanotify_mark.2: Document FAN_REPORT_FID and directory modification events")
