Bug#943343: fwupd: Workaround using dbus-broker

[Tj <debian@iam.tj>]

Package: fwupd
Version: 1.5.7-4
Followup-For: Bug #943343

Following Klaus Kudielka's discovery of the systemd bug and the finding
there that dbus-broker does not suffer the same problem as the dbus
reference implementation I installed "dbus-broker" following the
instructions at

https://github.com/bus1/dbus-broker/wiki

which boils down to:

apt install dbus-broker
systemctl enable dbus-broker.service
systemctl --global enable dbus-broker.service
systemctl reboot

$ sudo systemctl start fwupd-refresh
$ systemctl status fwupd-refresh
