Bug#920296: Installs /etc/systemd/system/dbus-org.freedesktop.timesync1.service identical to /lib/systemd/system/systemd-timesyncd.service

[Josh Triplett]

Package: systemd
Severity: normal

I installed using the Buster Alpha 4 installer, and for some reason I
ended up with a file
/etc/systemd/system/dbus-org.freedesktop.timesync1.service, identical to
/lib/systemd/system/systemd-timesyncd.service. dpkg -S shows it not
owned by any package, and searching through maintainer scripts pointed
to systemd's postinst. systemd shouldn't install a service in /etc
identical to the one already installed in /lib.
