useradd: modify check ID range for system users

useradd warns that a system user ID less than SYS_UID_MIN is outside the
expected range, even though that ID has been specifically selected with
the "-u" option.

In my opinion all the user ID's below SYS_UID_MAX are for the system,
thus I change the condition to take that into account.
