+ [Test Case]
+ 1. On a system that was previously crashing fwupd, ensure fwupd starts up
correctly.
+ 2. On a Dell system that previously works properly, ensure it continues to
work properly.

+ [Regression potential]
+ Regression potential is low, this fix only prevents plugins from running
where they shouldn't be running in the first place.
** Description changed:
[Impact]
On some non Dell systems that contain Synaptics MST hubs, fwupd will crash.
+ This affects fwupd 0.8.x in zesty. In Artful, fwupd will be synced to a
newer version from debian experimental (0.9.2-5) which contains this fix
already.
[Test Case]
1. On a system that was previously crashing fwupd, ensure fwupd starts up
correctly.
2. On a Dell system that previously works properly, ensure it continues to
work properly.
[Regression potential]
Regression potential is low, this fix only prevents plugins from running
where they shouldn't be running in the first place.
