Bug#1058749: scanbd: fails to upgrade from bookworm: mv: not replacing '/etc/scanbd/dll.conf'

Hi Andreas,

I'm unsure what to do here. This problem is triggered by a behaviour
change in coreutils.

With coreutils from unstable, scanbd from bookworm also fails to
install:

| Preparing to unpack .../scanbd_1.5.1-6+b1_arm64.deb ...
| Unpacking scanbd (1.5.1-6+b1) over (1.5.1-6+b1) ...
| Setting up scanbd (1.5.1-6+b1) ...
| mv: not replacing '/etc/scanbd/dll.conf'
| dpkg: error processing package scanbd (--configure):
|  installed scanbd package post-installation script subprocess returned error exit status 1
| Processing triggers for dbus (1.14.10-3) ...
| Errors were encountered while processing:
|  scanbd
| E: Sub-process /usr/bin/dpkg returned an error code (1)

I've marked this bug as found in the old version for now, and have
also opened #1058752 (but also see #1058630).
scanbd is not the only package affected by the coreutils change.
