David Ahern 76a8349dfd perf script: Fix format regression due to libtraceevent merge
Consider the commands:
    perf record -e sched:sched_switch -fo /tmp/perf.data  -a -- sleep 1
    perf script -i /tmp/perf.data

In v3.4 the output has the form (lines wrapped here)
    perf 29214 [005] 821043.582596: sched_switch:
prev_comm=perf prev_pid=29214 prev_prio=120
prev_state=S ==> next_comm=swapper/5 next_pid=0 next_prio=120

In 3.5 that same line has become:
    perf 29214 [005] 821043.582596: sched_switch:
<...>-29214 [005]     0.000000000: sched_switch:
prev_comm=perf prev_pid=29214 prev_prio=120
prev_state=S ==> next_comm=swapper/5 next_pid=0 next_prio=120

Note the duplicates in the output -- pid, cpu, event name. With
this patch the v3.4 output is restored:
    perf 29214 [005] 821043.582596: sched_switch:
prev_comm=perf prev_pid=29214 prev_prio=120
prev_state=S ==> next_comm=swapper/5 next_pid=0 next_prio=120

v3:
Remove that pesky newline too. Output now matches v3.4 (pre-libtracevent).

v2:
Change print_trace_event function local to perf per Steve's comments.
