    xsplice: Prevent new symbols duplicating core symbols
    
    When loading patches, the code prevents loading a patch containing a new
    symbol that duplicates a symbol from another loaded patch. However, the
    check should also prevent loading a new symbol that duplicates a symbol
    from the core hypervisor.
