ftests/009: add cpu controller format (v2)

Starting Linux Kernel version 6.0, the cpu controller cpu.stat (v2)
additionally displays force_idle statistics. It was introduced by
upstream commit 1fcf54deb767 ("sched/core: add forced idle accounting
for cgroups"). Append a new expected output with the field
'core_sched.force_idle_usec' to cgroup v2 valid output.
