perf tools: Fix missing string field printing in perf trace
Some string fields are not printed because of a missing printf
in the post-processing.
Before:
perf-10070 [000] 0.000000: sched_switch: task :10070 [120] (R) ==> :5720 [120]
geany-5720 [000] 0.000000: sched_switch: task :5720 [120] (S) ==> :10070 [120]
perf-10070 [000] 0.000000: sched_switch: task :10070 [120] (R) ==> :5720 [120]
geany-5720 [000] 0.000000: sched_switch: task :5720 [120] (S) ==> :10070 [120]
<idle>-0 [000] 0.000000: sched_switch: task :0 [140] (R) ==> :361 [115]
After:
perf-10070 [000] 0.000000: sched_switch: task perf:10070 [120] (R) ==> geany:5720 [120]
geany-5720 [000] 0.000000: sched_switch: task geany:5720 [120] (S) ==> perf:10070 [120]
perf-10070 [000] 0.000000: sched_switch: task perf:10070 [120] (R) ==> geany:5720 [120]
geany-5720 [000] 0.000000: sched_switch: task geany:5720 [120] (S) ==> perf:10070 [120]
<idle>-0 [000] 0.000000: sched_switch: task swapper:0 [140] (R) ==> kondemand/1:361 [115]
