Bug#1041237: sddm: D-Bus policy is installed in /etc instead of /usr

[Gioele Barabucci <gioele@svario.it>]

Package: sddm
Version: 0.20.0-1
Tags: patch

Dear sddm maintainers,

sddm installs its D-Bus policy file in `/etc/dbus-1`. Since Debian 9 the 
standard directory for package-installed dbus policies is 
`/usr/share/dbus-1`.

See: https://bugs.debian.org/1006631

Lintian complains with `dbus-policy-in-etc`.

A patch to fix this issue is available at

https://salsa.debian.org/qt-kde-team/3rdparty/sddm/-/merge_requests/6

Regards,
