perf tools: Unify swapper tasks naming
In perf tools, we hardcode the pid 0 cmdline resolving to
"idle" because the init task is not included in the COMM
events.
But the idle tasks secondary cpus are resolved into their
"init" name through the COMM events.
We have then such strange result in perf report (ditto with
trace):
19.66% init [kernel] [k] acpi_idle_enter_c1
17.32% [idle] [kernel] [k] acpi_idle_enter_c1
It's then better to unify the swapper tasks into a single init
name.
