    x86/shadow: depend on PV || HVM
    
    With the building of guest_?.o now depending on PV or HVM, without
    further #ifdef-ary shadow code won't link anymore when !PV && !HVM.
    Since this isn't a useful configuration anyway, exclude shadow code from
    being built in this case.
    
    Fixes: aff8bf94ce65 ("x86/shadow: only 4-level guest code needs building 
when !HVM")
