[libsoup] soup-server: simplify default-handler special-casing

    soup-server: simplify default-handler special-casing
    
    We don't need an explicit default_handler variable; if we put a
    handler into the map at the right path, then it's the default
    automatically.
    
    Also, move the default path special-casing into a macro.
