Some tests produce format-dependent output. Either the difference is
filtered out and ignored, or the test case is format-specific so we
don't need to worry about per-format output differences.
There is a third case: the test script is the same for all image formats
and the format-dependent output is relevant. An ugly workaround is to
copy-paste the test into multiple per-format test cases. This
duplicates code and is not maintainable.
This patch allows test cases to add per-format golden output files so a
single test case can work correctly when format-dependent output must be
checked:
123.out.qcow2
123.out.raw
123.out.vmdk
...
This naming scheme is not composable with 123.out.nocache or 123.pc.out,
two other scenarios where output files are split. I don't think it
matters since few test cases need these features.
