[PATCH] adduser: Make home directory not world readable

[Valentin]

 > this is the default in debian

Thank you for explaining the historical context. Is this *just* the 
historical context or do you mean that busybox *should* follow debian? 
If it is the latter, would busybox change the default if debian did so 
first?

 > This could be made a config option

Do you mean a config option in a config file or a command line argument? 
adduser currently does not parse any config file and I do not want to 
make that part of this change. Adding a command line argument for the 
mode is a smaller change but even that I would rather not make part of 
this change.
