    x86/shim: Fix defconfig selection and trim the build further
    
    Several options (TBOOT, XENOPROF, Scheduler) depend on EXPERT to be able to
    deselect/configure.
    
    Enabling EXPERT now causes the request of the Credit1 scheduler to be 
honoured
    (rather than giving us Credit2), but take this opportunity to switch to 
Null,
    as the previously problematic issues are now believed to be fixed.
    
    Enabling EXPERT also allows XEN_SHSTK to be selected, and we don't want this
    being built for shim.  We also don't want TRACEBUFFER or GDBSX either.
    
    Take this oppotunity to swap the disable of HVM_FEP for a general disable of
    HVM (likely to have wider impliciations in the future), and disable ARGO 
(will
    necesserily need plumbing work to function in shim).
