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.
