[PATCH 2/3] KVM: selftests: Add missing newline to access_tracking_perf_test help

[Zenghui Yu <zenghui.yu@linux.dev>]

From: "Zenghui Yu (Huawei)" <zenghui.yu@linux.dev>

The help text for the -h option is printed without a trailing newline, so
it runs together with the first line of the guest mode help that follows
it.  Add the missing newline.
