CTest: add test failure reason to JUnit XML output

In case of test failure, add the test failure reason (e.g. "Timeout") to the failure message in the XML file. This is the same value that is shown in the ctest text output. Fixes: #24184

    In the Python subprocess, RPCServer is instantiated with handlerclass

    the mix-in class SocketIO.

    When the RPCServer 'server' is instantiated, the TCPServer initialization
    creates an instance of run.MyHandler and calls its handle() method.
    handle() instantiates a run.Executive object, passing it a reference to the
    MyHandler object.  That reference is saved as attribute rpchandler of the
    Executive instance.  The Executive methods have access to the reference and
    can pass it on to entities that they command
    (e.g. RemoteDebugger.Debugger.start_debugger()).  The latter, in turn, can
    call MyHandler(SocketIO) register/unregister methods via the reference to
    register and unregister themselves.
