Bug#923115: cups-client: cupsctl needs to edit `cups-files.conf`

[Paul Menzel <pmenzel@molgen.mpg.de>]

Package: cups-client
Version: 2.2.10-4
Severity: normal

Dear Maintainer,


`/usr/sbin/cupsctl FileDevice=No` edits `/etc/cups/cupsd.conf` instead 
of `/etc/cups/cups-files.conf`.

```
/etc$ /usr/sbin/cupsctl FileDevices=No
/etc$ sudo git diff
diff --git a/cups/cupsd.conf b/cups/cupsd.conf
index 02afed2..c347852 100644

Kind regards,

Paul
