tracepoint: Print the function symbol when tracepoint_debug is set

Browse source 
When tracepoint_debug is set, we may get the output in kernel log:
     [  380.013843] Probe 0 : 00000000f0d68cda

It is not readable, so change to print the function symbol.
After this patch, the output may becomes:
     [   55.225555] Probe 0 : perf_trace_sched_wakeup_template+0x0/0x20
