adduser.sh: Add info which separator to use in the question itself

During the non-root user setup (adduser.sh), people are often confused
what the separator is when they are asked which groups to join the new
user into. For example, wheel and operator: users often assume that the
two groups are separated by a comma (and maybe even a space after it),
but the script will check for that and refuses such entries.

Help the users by mentioning that the groups need to be space separated
in the question itself. That way, it does not take up extra space and
avoids confusion about what the separator is.
