[LTP] [PATCH 2/4] syscalls/fanotify09: Verify if no events are expected

[Amir Goldstein <amir73il@gmail.com>]

Some test cases expect no events for non-first groups and some expect
one event on non-dir child for non-first groups, but it is not verified
that non-first groups get the desired amount of events, so add this
information to the test case definition.
