[kvm-unit-tests PATCH 5/8] x86/hyperv: skip hyperv-clock test if unsupported by host

[Nadav Amit <nadav.amit@xxxxxxxxx>]

From: Nadav Amit <nadav.amit@xxxxxxxxx>

Skip the hyperv-clock tests if time reference counter is unsupported by
the host, similarly to the way other hyperv tests first check support of
the host.
