Right now, skipped tests are returning a failure exit code if /dev/kvm does
not exists. Consistently return a zero status code so that various scripts
over the interwebs do not complain. Also return a zero status code if
the KVM_CAP_SYNC_REGS capability is not present, and hardcode in the
test the register kinds that are covered (rather than just using whatever
value of KVM_SYNC_X86_VALID_FIELDS is provided by the kernel headers).

The test checks the behavior of setting MSR_IA32_TSC in a nested guest,
and the TSC_OFFSET VMCS field in general. It also introduces the testing
infrastructure for Intel nested virtualization.

This includes the infrastructure to map the test into the guest and
run code from the test program inside a VM.
