tests: v4l2_compat: Prettify failure output

When a test is being run on a video device, there is output like so:

Testing /dev/video0 with uvcvideo driver...

and when it succeeds, "success" is appended:

Testing /dev/video0 with uvcvideo driver... success

On failure, however, the output of v4l2-compliance is printed before
"failure" is printed, resulting in the first line of the v4l2-compliance
output to be printed on the same line as the message:

Testing /dev/video2 with uvcvideo driver... v4l2-compliance SHA: not available, 64 bits
<v4l2-compliance output>
failure

Refactor the code to make "failure" print before the output of the test,
to prettify the output upon failure.
