Extractcode replaces `:` in file names with `_`

This replacement is causing an issue with how debian system package resources are found and associated in the scancode.io docker pipeline. Some debian `.list` files have `:` in their names to separate the architecture from the package name, e.g. `libc6:amd64.list`. However, extractcode extracts this file as `libc6_amd64.list`. The code run in the docker pipeline is trying to find the original, unmodified name (`libc6:amd64.list`), and such the pipeline does not find the declared resources of a package from the `.list` as it was extracted as `libc6_amd64.list`
