Also print a warning if umockdev-run is too old. Note that we still try to run the unreliable tests as they are still useful for development.
As the driver is not a normal image device, we need to add a custom script to test it. Note that the ioctl dump must also be manually modified unfortunately as the state is tracked incorrectly for the device by umockdev-record.
Initially only the vfs5011 driver is tested. Please note that these tests will be unreliable before umockdev 0.13.2. See also https://github.com/martinpitt/umockdev/pull/92
