Create an evil testcase to ensure we also unload when the device is
still sort of active.

igt_create_fb will create a framebuffer and probably a backing BO,
while I also saw a crash related to property blobs.

This tests that we can teardown with buffer objects,
property blobs and framebuffers on the list.

There should probably be another test for a VM and engine too,
but this should be enough for a first attempt.
