selftests: KVM: Test KVM_X86_QUIRK_FIX_HYPERCALL_INSN

Browse source

Add a test that asserts KVM rewrites guest hypercall instructions to
match the running architecture (VMCALL on VMX, VMMCALL on SVM).
Additionally, test that with the quirk disabled, KVM no longer rewrites
guest instructions and instead injects a #UD.
