    xen/Kconfig: livepatch-build-tools requires debug information
    
    The tools infrastructure used to build livepatches for Xen
    (livepatch-build-tools) consumes some DWARF debug information present in
    xen-syms to generate a livepatch (see livepatch-build script usage of 
readelf
    -wi).
    
    The current Kconfig defaults however will enable LIVEPATCH without 
DEBUG_INFO
    on release builds, thus providing a default Kconfig selection that's not
    suitable for livepatch-build-tools even when LIVEPATCH support is enabled,
    because it's missing the DWARF debug section.
    
    Fix by defaulting DEBUG_INFO to enabled when LIVEPATCH is.
