packages: release: test: really fail when files are missing from ${release_files}.

We have a test for catching a situation where new files are added in
releases without adding them as well in the ${release_files} variable
to test for their existance.

But this test only warn of the issue instead of failing. And since
people might not inspect all the log details in depth, it's better to
fail instead.
