Correct aarch64 KPTI dmesg message
As it's seen in unmap_kernel_at_el0 (both the function definition and its usage in arm64_features[]) from arch/arm64/kernel/cpufeature.c the kernel reports this string: CPU features: detected: Kernel page table isolation (KPTI) or (before commit e0f6429dc1c0 ("arm64: cpufeature: Remove redundant "feature" in reports")): CPU features: detected feature: Kernel page table isolation (KPTI) if KPTI is enabled on the system. So on let's adjust check_variant3_linux() to make it grep these strings if executed on an aarch64 platform. Tested on a Cavium ThunderX2 machine.
