The event 'timer:hrtimer_setup' is relatively new, for older kernels,
perf trace enum tests won't run as the event 'timer:hrtimer_setup'
cannot be found.

It was originally called 'timer:hrtimer_init', before being renamed in:

commit 244132c4e577 ("tracing/timers: Rename the hrtimer_init event to hrtimer_setup")

Using timer:hrtimer_start should be enough for current testing, and
hopefully 'start' won't be renamed in the future.

Before:
    $ sudo /tmp/perf test enum -vv
    107: perf trace enum augmentation tests:
    107: perf trace enum augmentation tests                              : Running
    --- start ---
    test child forked, pid 786187
    Checking if vmlinux exists
    Tracing syscall landlock_add_rule
    Tracing non-syscall tracepoint timer:hrtimer_setup,timer:hrtimer_start
    [tracepoint failure] Failed to trace timer:hrtimer_setup,timer:hrtimer_start tracepoint, output:
    event syntax error: 'timer:hrtimer_setup,timer:hrtimer_start'
			 \___ unknown tracepoint

    Error:  File /sys/kernel/tracing//events/timer/hrtimer_setup not found.
    Hint:   Perhaps this kernel misses some CONFIG_ setting to enable this feature?.

    Run 'perf list' for a list of valid events

     Usage: perf trace [<options>] [<command>]
	or: perf trace [<options>] -- <command> [<options>]
	or: perf trace record [<options>] [<command>]
	or: perf trace record [<options>] -- <command> [<options>]

	-e, --event <event>   event/syscall selector. use 'perf list' to list available events
