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 trace requires root because it needs to use tracepoints and BPF.
Skip those test when it's not run as root.
Before:
$ perf test trace
15: Parse sched tracepoints fields : Skip (permissions)
80: perf ftrace tests : Skip
105: perf trace enum augmentation tests : FAILED!
106: perf trace BTF general tests : FAILED!
107: perf trace exit race : FAILED!
118: probe libc's inet_pton & backtrace it with ping : Skip
125: Check Arm CoreSight trace data recording and synthesized samples: Skip
127: Check Arm SPE trace data recording and synthesized samples : Skip
132: Check open filename arg using perf trace + vfs_getname : FAILED!
After:
$ perf test trace

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.

Shellcheck versions < v0.7.2 can't follow this path so add the helper to
fix the following warning:
In tests/shell/trace_btf_enum.sh line 13:
. "$(dirname $0)"/lib/probe.sh
^--------------------------^ SC1090: Can't follow non-constant source.
Use a directive to specify location.

enums in 'perf trace'
Trace landlock_add_rule syscall to see if the output is desirable.
Trace the non-syscall tracepoint 'timer:hrtimer_init' and
'timer:hrtimer_start', see if the 'mode' argument is augmented,
the 'mode' enum argument has the prefix of 'HRTIMER_MODE_'
in its name.
