ARM/Aarch64 /proc/cpuinfo has no virtualization related flags.
Refactor the Qemu/KVM test a bit:
1) run the "for hardware virtualization" test only on plaforms with known
cpuinfo flags (x86, s390)
2) test for /dev/kvm also on platforms where no cpu flags are set
Finally Add a more generic error hint message for non-x86 plaforms
when /dev/kvm is missing.
