Bug description:
[IMPACT]
In xenial lscpu prints the wrong "Hypervisor vendor" and
"Virtualization type" on PowerVM or KVM systems. Incorrect hypervisor
and virtualization type reported in ubuntu 16.04.04 guest running in
P8compat mode on P9 boston-LC.

[Potential Regression]
The fix changes the logic to how lscpu-dmi returns from read_hypervisor_dmi()
this could introduce potential regression in platforms that has incorrect DMI
information.
