[LTP] [PATCH v3 1/3] syscalls/fanotify: Add a helper macro which checks for the presence of specific fanotify initialization flag(s)

[Matthew Bobrowski]

This is a trivial macro that can be used throughout fanotify tests to
check whether the underlying running kernel supports the supplied
fanotify initialization flag(s).
