Bug#1000179: cme update dpkg-copyright should detect cpoyright holders for apache license

[Dominique Dumont]

Hi

Unfortunately, cme dpkg relies on licensecheck to get copyright info from 
files.

licensecheck does not detect the copyright statement from LICENSE file:

$ licensecheck LICENSE
LICENSE: *No copyright* Apache License 2.0

In this case, cme assumes this is a plain license file and skips this file hence 
you get no information for golang-github-go-git-go-billy

For the record, golang-github-go-git-go-billy can be found there:

https://salsa.debian.org/go-team/packages/golang-github-go-git-go-billy

All the best
