    Remove trailing '-' from the last QTDP action packet

    The has_more predicate in remote_target::download_tracepoint always
    evaluates to true, so the last action packet will be sent with a
    trailing '-'.  This patch changes the predicate to remove the last
    trailing '-'.

            * remote.c (remote_target::download_tracepoint): Fix the has_more
            predicate in the QTDP action list iteration.
