refactor(poetry): Improve the definition file paths

In order to do it's job, `Poetry.kt` generates a requirements file and
then relies on `Pip.kt` to do the analysis. The resulting
`ProjectAnalyzerResult`s uses the paths to these generated requirements
files as definiton file paths. This does not make sense, because:

1. The generation of the files is an implementation detail.
2. The generated files do not exist in the code repository which can
   lead to confusion, in particular also these get referenced from
   ORT configuration / path excludes.

Fix that by patching up the `ProjectAnalyzerResult`s to recover the
original definition file name.
