perf test trace_btf_enum: Add regression test for the BTF augmentation of 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.

Committer testing:
