Use !hypervisor_is_type(X86_HYPER_NATIVE) checks

ffe782df80 UBUNTU: SAUCE: smpboot: reuse timer calibration
 -> do this by default on paravirt machines, or potentially kvm only machines

3b458961f1 UBUNTU: SAUCE: Increase the ext4 default commit age
 -> do this by default on paravirt machines, or potentially kvm only machines

4983291d45 UBUNTU: SAUCE: [kvm] tsc: make no_timer_check default to 1
 -> do this by default on paravirt machines, or potentially kvm only machines

bd43e884f4 UBUNTU: SAUCE: [kvm] tsc: make tsc= default to reliable
 -> kvm init should do what vmware init is doing and setting TSC_RELIABLE capability
                wrmsrl(HV_X64_MSR_TSC_INVARIANT_CONTROL, 0x1);
                setup_force_cpu_cap(X86_FEATURE_TSC_RELIABLE);

And then we should change config to move virtio & ext4 filesystems as built in.
