description:
In guess-license, use ninka for determining the licenses.

Ninka can be installed from wip/ninka and analyzes each file individually,
thereby providing a much more detailed analysis than the ad-hoc method that
only looks at some COPYING files.

If Ninka is not installed, the naive fallback continues to be used.
