Ticket 47473 - setup-ds.pl doesn't lookup the "root" group correctly

Bug Description:  Silent install will fail, if you set the "SuiteSpotUserID"
                  to root, but do not set "SuiteSpotGroup".

Fix Description:  The root gid is zero, and this incorrectly triggered an
                  error that cancelled the install.  Fix is to check if the
                  user info is set, instead of checking the group id value;
