Subject: [RFC PATCH 3/5] kselftests/resctrl: remove unnecessary exclude_idle

The Linux manual states regarding exclude_idle: "While you can currently
enable this for any event type, it is ignored for all but software events."
Also, it appears exclude_idle is not supported on Arm.
Therefore, remove it.
