The FAN_REPORT_FID and fanotify_event_info_fid were introduced
in v5.1. Currently there is no check if the kernel supports it
making xfstests build to fail on older kernels.
Fixes: 29d120e41c3d ("generic: test fsnotify filesystem error reporting")

I think this was mainly to allow for IRIX back when fstests ran there, the
last of which were removed by
bc2568f9 fstests: remove IRIX test program open_unlink
A lot of the more recent programs in TARGETS look like they wouldn't apply
to anything outside of linux, i.e. t_ext4_dax_journal_corruption and
t_ext4_dax_inline_corruption.
Given the use of configure to decide what to compile in it may be clearer
if this was just simplified to use TARGETS in the long term.

Ok, let's just stick with this version and I will try too look into
unifying
of the targets.
