tracing/timers: Rename the hrtimer_init event to hrtimer_setup

The function hrtimer_init() doesn't exist anymore. It was replaced by
hrtimer_setup().

Thus, rename the hrtimer_init trace event to hrtimer_setup to keep it
consistent.

perf test: Skip syscall enum test if no landlock syscall

The perf trace enum augmentation test specifically targets landlock_
add_rule syscall but IIUC it's an optional and can be opt-out by a
kernel config.

Currently trace_landlock() runs `perf test -w landlock` before the
actual testing to check the availability but it's not enough since the
workload always returns 0. Instead it could check if perf trace output
has 'landlock' string.
