    xen: stop trying to use the system <stdarg.h> and <stdbool.h>
    
    We already have our own versions of the stdarg/stdbool definitions, for
    systems where those headers are installed in /usr/include.
    
    On linux, they're typically installed in compiler-specific paths, but
    finding them has proved unreliable.  Drop that and use our own versions
    everywhere.
