According to section "Checks on VMX Controls" in Intel SDM vol 3C,
the following check needs to be enforced on vmentry of L2 guests:
If the "virtual-interrupt delivery" VM-execution control is 1, the
"external-interrupt exiting" VM-execution control must be 1.
KVM already has the necessary check in it, we just need a unit test. This
patch builds on top of my previous patch (that I sent out on this alias
earlier) in that the code in this patch uses the test_apic_ctls() function
that was added by the former.
