KVM: selftests: Verify KVM stuffs runtime CPUID OS bits on CR4 writes
Extend x86's set sregs test to verify that KVM sets/clears OSXSAVE and
OSKPKE according to CR4.XSAVE and CR4.PKE respectively. For performance
reasons, KVM is responsible for emulating the architectural behavior of
the OS CPUID bits tracking CR4.
