5e7cb71570 KVM: selftests: Convert kvm_clock_test away from VCPU_ID
Convert kvm_clock_test to use vm_create_with_one_vcpu() and pass around a
'struct kvm_vcpu' object instead of using a global VCPU_ID.

Opportunistically use vcpu_run() instead of _vcpu_run() with an open
coded assert that KVM_RUN succeeded.

61fb1c5485 selftests: KVM: Add test for KVM_{GET,SET}_CLOCK
Add a selftest for the new KVM clock UAPI that was introduced. Ensure
that the KVM clock is consistent between userspace and the guest, and
that the difference in realtime will only ever cause the KVM clock to
advance forward.
