I troubleshoot this issues and this issue is caused by systemd not
correctly setting the permission despite being configured that way (see
Debian bug #919231). Therefore I re-assign it to the systemd package.

When the installation of salt-master fails, it is enough to reboot the
machine. The service successfully starts on the next boot.

Working setup:

* Debian unstable as of 2020-01-28
* salt 2018.3.4+dfsg1-7
* systemd 244.1-1

* Debian 10 as of 2020-01-28
* salt 2018.3.4+dfsg1-6
* systemd 244-3~bpo10+1 (from buster-backports)

Not working:

* Debian 10 as of 2020-01-28
* salt 2018.3.4+dfsg1-6
* systemd 241-7~deb10u2

Output of a working setup:

```
