lscpu: read_hypervisor_dmi: only fallback to memory scan on x86/x86_64

As the comment in the code says, this method is really only valid
on x86 and x86_64, so add a #ifdef for those architectures around
that code block.

This was causing "Program lscpu tried to access /dev/mem between f0000->100000."
warnings on some ppc64 machines.
