Old build script code was limiting cpu to power8 when building on power9 always.
As this blocks any future development and also is only done on this particular platform this way we change it by default. So KVM on power9 is not special anymore and uses the cpu by default as with any other architecture or VM type.
A buildflag kvm-max-cpu-compat-power8 can be set to restore the old behaviour.
