ROX-14082: Create test files and symlinks from code

[msugakov]

Create test files and symlinks from code instead of static files.

One of them being an absolute link breaks Cachito with the following error:

Image build failed. Error in plugin resolve_remote_source: Cachito request is in "failed" state, reason: The destination of 'pkg/analyzer/nodes/testdata/rootfs-rhcos/etc/redhat-release' is outside of cloned repository. Request 576595 (https://cachito.engineering.redhat.com/api/v1/requests/576595/logs) tried to get repo 'https://github.com/stackrox/scanner.git' at reference '3432ef813ebc20a007d185a ..

Testing

I compared the contents of former testdata
