qemu-img is listed as 'R' (required) in the README file.  The reason
it's needed is because we're now building some qcow2 test images in
tests/data.

In Fedora we split qemu-img off into a separate subpackage that
doesn't depend on the main qemu package.

I believe it may work if you change noinst_DATA -> check_DATA.
I don't think we use the test files outside the tests.
