perf probe: Show trace event definition
Add --definition/-D option for showing the trace-event definition in
stdout. This can be useful in debugging or combined with a shell script.
e.g.
----
# perf probe --definition 'do_sys_open $params'
p:probe/do_sys_open _text+2261728 dfd=%di:s32 filename=%si:u64 flags=%dx:s32 mode=%cx:u16
