D351: demandimport: disable if chg is being used

[yuja (Yuya Nishihara)]

  > Instead of running `hg serve --cmdserver chgunix ...`, chg client executes `chgserve ...`. And the hg script could notice that by checking `sys.argv[0]` and does some special handling
  
  At this point, I don't think it's simpler than using CHGINTERNALMARK or HGDEMANDIMPORT.
  
  We might need another entry point for chg in future for some reason, but that is the last option IMHO.
