perf tools: Resolve idle thread cmdline for perf trace
The cmd-trace tool used the cmdline file and resolved the idle
thread using a hardcoded check for the 0 task pid.
Now we have a centralized way to do that from perf using
register_idle_thread() API.
Before:
:0-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name
:0-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name
After:
[idle]-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name
[idle]-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name
