Move remaining AUM tests to Fixed Function
On commit 2d75d3c0 several tests have been moved to Fixed Function in order to follow the guideline to run all the AUM tests on this type of images. However, apertis-update-manager-amd64-rollback test is still run on HMI images, which has no sense. Move this test to Fixed Function in order to follow the guideline.
