[Netkit.users] Minor vstart script bug when using --print with --ethN

[Kris Olander]

The code in the "ensureHub" routine will hang if you specify the  
--print and --ethN command arguments together.

The socket doesn't get created when you are only interested in printing  
the command and the "busy/wait" code will wait forever since the socket  
wasn't actually created.

I fixed this in the 1.4.2 vstart by simply moving all the busy/wait  
code to reside under the conditional check for only printing out the  
command.

----------------------------------
         if not justPrint: system(command)

     #busy wait until the file for the socket is created
     exists=0
     while not exists:
         try:
             stat(sock)
             exists=1
         except:
             pass

----to this---
         if not justPrint:
            system(command)
     #busy wait until the file for the socket is created
            exists=0
            while not exists:
                try:
                    stat(sock)
                    exists=1
                except:
                    pass
