    base-files: treat 'ipaddr is inside range' as warning again
    
    The call to 'ipcalc' is used in 'dnsmasq' init script to create the
    configuration. If the 'ipaddr' is in the configured range then 'ipcalc' exited
    with an error whereby the START/STOP variables are unavailable.
    
    This behaviour has changed during 'ipcalc' refactoring and now leads to a
    problem when starting 'dnsmasq' if the 'ipaddr' is inside this range. To
    restore the old behaviour, only a warning is issued as before and the
    required variables for the 'dnsmasq' are still set.
    
    Fixes: 854739b32c7f (base-files: ipcalc.sh: Rewrite in pure shell)
