Provide `name` attribute in packages files summary

[tdruez]

In the summary, packages section. For each package a files entry is available.
It would be useful to provide the name value along the current path and type.

@tdruez thank you. That's indeed a relatively easy one. The place where these "files" attributes are added in the packages summary is controlled by the skinny arg https://github.com/nexB/scancode-toolkit/blob/0b259aaafef6d823cd0051c920968a8379dc26ae/src/summarycode/summarizer.py#L469

it may need a bit of thinking though as adding the name at all times may or may not be OK.
