Fix Arch kernel image detection ( #268 )
...
currently, the script tries to use the wrong kernel image on Arch if an
alternative kernel (hardened, zen, or lts) is in use. Fortunately, all
the Arch kernel packages place a symlink to the kernel image as /usr/lib/modules/$(uname -r)/vmlinuz, so simply removing the guess for Arch fixes the issue.

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.
