    Double allocated varnishlog buffer space.
    
    Extensive test cases often lead to a lot of log output,
    which at times tripped the following assert:
    
    Assert error in vtc_log_emit(), vtc_log.c line 122:
      Condition(vtclog_left > l) not true.
    
    Double the amount of buffer space allowed to avoid this. Another 256KB
    memory use per concurrent running test should be fine.
