KVM: selftests: Make hyperv_clock require TSC based system clocksource
KVM sets up Hyper-V TSC page clocksource for its guests when system
clocksource is 'based on TSC' (see gtod_is_based_on_tsc()), running
hyperv_clock with any other clocksource leads to imminent failure.
Add the missing requirement to make the test skip gracefully.
