[PATCH v2 3/4] x86/shim: don't permit HVM and PV_SHIM_EXCLUSIVE at the same time



This combination doesn't really make sense (and there likely are more);
in particular even if the code built with both options set, HVM guests
wouldn't work (and I think one wouldn't be able to create one in the
first place). The alternative here would be some presumably intrusive
#ifdef-ary to get this combination to actually build (but still not
work) again.
