executed command snapshot

busybox executes "addgroup" when "adduser" command is executed.
This is with 1.21.1 version of busybox cross-compiled for ARM with arm-linux-gnueabi- toolchain.

The bug is that "adduser" with no params should error out, but there is no check for that. So it trues to create NULL user.

For that, it runs "addgroup -- <NULL> users" which isn't going to work - it prints help instead.

Fixed in git.
